Question

Can someone please help me with -1/4(x-12)+1/2(x+2)=x+4 , Linear Equations!

Answer 1

ok i like to use numbers instead of fractions so first of all

-1/4 = -0.25
1/2 = 0.5

so

-1/4(x-12)+1/2(x+2)=x+4

would be

-0.25(x - 12) + 0.5(x + 2) = x + 4

which is

-0.25x + 3 + 0.5x + 1 = x + 4

put it in order

0.5x - 0.25x + 1 + 3 = x + 4

which is

0.25x + 4 = x + 4

now we rearrange to bring the numbers to one side and the variables to the other side
which gives you

0.25x - x = 4 - 4

0.25x - x = 0

-0.75x = 0

anything multiplied by 0 will always give the answer 0 hence why x is 0

x = 0

it cant be any other answer

dont forget to click good answer :)
