Solve: 4(x + 6) = 6(x − 2) plesase answer it , and if you can explain how you got that it would be great ..
first use the distributive property multiply the 4 times each term inside the parens
for example 4(x+6) means 4 times x plus 4 times 6 can you do that?
4x6 = 24 ? like that ?
you start with 4(x + 6) = 6(x − 2) now on the left side of the = sign do 4 times x plus 4*6 you get 4x+24= 6(x-2) can you do the right side (multiply 6 times each term inside the parens)
6x2 = 12 ? 6times X = 6x ?
what is 6*x?
6x ?
what is 6* -2?
-12
what is 6*(x-2) ?
Not getting it ? 6times -2 = -12 and 6times X = 6X
yes, but added together what is 6*(x-2) ?
-12 - 6x ?
where did you get -6x isn't 6*x just 6x what is 6*(x-2) ?
I thought it was -12 minus 6x ?
what is 6*(x-2) ?
6x and -12
people don't say and when they mean plus what is 6*(x-2) ?
6x + -12
ok, so we started with 4(x + 6) = 6(x − 2) we distribute the 4 (on the left) and the 6 on the right to get 4x+24= 6x + -12 next, add 12 to both sides of the equation.
Where do i add the 12 ?
to both sides of the equation
4x+24= 6x + -12 add 12 to the left side and to the right side of the = sign
so you will end up with 4x +36=6x
then move your 4x to the other side and you get 36=6x-4x
4x+36
@maktaopvp write out the full equation, with the = sign 4x+24= 6x + -12 add 12 to the left side and to the right side of the = sign
then add the -4x +6x and you get 36=2x then divide by 2 on each side
4x+36=18x+-12 ?
you need to add 12 to both sides where is the +12 on the right side?
Okay i add 12 to the 24 and where else ?
on the right side of the = sign
so to the 6x ?
yes, but write out the whole equation
4x + 36 = 18 + -12 ??
you start with 4x+24= 6x + -12 add +12 to both sides. NOTE: 6x+12 is not 18 and it is not 18x. just write +12 on both sides
4x + 24 +12 = 6x + -12 +12 ??
yes. now you can add the "pure numbers" (the terms without the x) what do you get? (Write out the whole equation)
4x + 36= 6x and 12- + 12 = 0 ?
yes, you get 4x + 36= 6x (because 12-12 = 0) now add -4x to both sides just write -4x on both sides
4x + 36 + -4 = 6x + -4 ?
no, not -4, -4x (the x is important)
so its 4x + 36 + -4 = -4x ?
its very easy 4x +24 = 6x-12 -2x=-36 x=18
4x + 36= 6x write -4x on both sides
4x + 36 -4x = 6x -4x ?
yes now on the left side if you have 4 x's and you take away 4 x's, how many x's do you have?
0
so the left side is just 36 (because 4x-4x =0 and 36+0 is 36) 36= 6x-4x what is the right side?
2x?
yes, but write out the whole equation
36= 2x
OK, if 2 x's are 36 how much is 1 x?
18
x=18 is the answer. the way to do it is 36=2x divide both sides by 2 36/2 = 2x/2 18=x
ahh okay thanks alot
If you go over what we did, you might be able to solve other problems like this one.
