start by multiplying (2x + 2) by 1/2
OpenStudy (nptweezy):
@blurbendy I got
OpenStudy (blurbendy):
you multiplied by 5, not 1/2
1/2 = 0.5, not 5
OpenStudy (blurbendy):
just take have of 2x and half of 2

ohhhh I fixed it and got x+1 @blurbendy
OpenStudy (blurbendy):
okay, now multiply (3x and -1) by -1/4
OpenStudy (nptweezy):
ok i don't know how to do that i put it in a calculator and got 1/4 (3x+1) @blurbendy
OpenStudy (blurbendy):
-1/4 * 3x = -3/4x
-1/4 * 1 = -1/4
OpenStudy (blurbendy):
so you have x + 1 -3/4x - 1/4
= -3/4x + x -1/4 + 1
Combine like terms

x+1-3/4x + x -1/4 + 1
OpenStudy (nptweezy):
@blurbendy
OpenStudy (blurbendy):
what is (-3/4x + x) ?
OpenStudy (nptweezy):
i have no idea im confused now im just rying to find out what x is @blurbendy
OpenStudy (anonymous):
multiply by 4 on both sides and then solve brackets using distributive property.

OpenStudy (blurbendy):
you don't solve for x yet. just ask yourself what is (-3/4 + 1) ?
OpenStudy (nptweezy):
1/4 @blurbendy
OpenStudy (blurbendy):
good, so you have 1/4x + (-1/4 + 1)
what is (-1/4 + 1) ?
OpenStudy (nptweezy):
3/4 @blurbendy
OpenStudy (anonymous):
\[4*\frac{ 1 }{ 2 }\left( 2x+2 \right)-4*\frac{ 1 }{4 }\left( 3x-1 \right)=4*15\]
2(2x+2)-(3x-1)=60
4x+4-3x+1=60
solve it.

OpenStudy (blurbendy):
okay, so you have 1/4x + 3/4 = 15
subtract 3/4 from both sides
what is 15 - 3/4?
OpenStudy (nptweezy):
57/4 @blurbendy
OpenStudy (nptweezy):
that or 3 @blurbendy
OpenStudy (blurbendy):
okay so you have
1/4x = 57/4
multiply both sides by 4
what is 57/4 * 4 ?
OpenStudy (nptweezy):
4 @blurbendy

messed up our math somewhere, it should be 55/4 *4, x = 55
OpenStudy (nptweezy):
ok now I'm really confused 1/4 x equals 4 and 4*4 is 16
OpenStudy (anonymous):
x+5=60
x=60-5=55
OpenStudy (nptweezy):
thanks @blurbendy @surjithayer yall both got the answer right thank you for the help
OpenStudy (blurbendy):
np!
