12x-3=8x+9

12x-3= 9-8x

4x - 3 = 9

4x = 9 + 3

4x = 12

x = 12/4

x = 3

4(x-5)-3(x-2)=6

(4x - 20) - (3x - 6) = 6;

x - 14 = 6;

x = 6 + 14;

x = 20
solve for x. 3(x-2)+5(x+3)=33
Question
Updated 2/19/2015 10:20:31 PM
3(x - 2) + 5(x + 3) = 33;
3x - 6 + 5x + 15 = 33;
8x + 9 = 33;
8x = 33 - 9;
8x = 24;
x = 24/8;
x = 3
solve for x. 8(x+3)=7(x+3)
Question
Updated 10/9/2016 9:23:51 PM
8(x + 3) = 7(x + 3)
8x + 24 = 7x + 21
8x + 24 = 21 - 7x
x + 24 = 21
x = 21 - 24
x= - 3
9x+4=8x+5
Weegy: If you simplify that, the answer will be X? + X. User: solve for x. 9x+4=8x+5 (More)
