=> 4x+32-4 = -15x+15-7x
=> 4x+15x+7x = 15+4-32
=> 26x = -13
=> x = -13/26 = -1/2

4(x+8) -4= - 5(3x -3) - 7x
4x+32-4 = -15x+15-7x
4x+7x+15x = 15-32+4
26x = -13
x -13/26 = -1/2 or -0.5
ans x = -0.5

4(x+8) -4= - 5(3x -3) - 7x
First expand the brackets
4x+32-4=-15x+15-7x
Then get the x's on one side and numbers on the other
REMEMBER: swop sides, swop signs
4x+15x+7x= -32+4+15
26x = -13
x = -13/26 = -0.5

4x + 32 - 4 = -15x + 15 -7x
26x = -13
x = -13/26
= -1/2

4(x+8) -4= - 5(3x -3) - 7x?
4x+32-4=-15x+15-7x
4x+28=-22x+15
4x+13=-22x
13=-18x
-13/18=x

4x + 32 - 4 = -15x - 15 - 7x
4x + 15x + 7x = -15 - 32
26x = -47
x= -47/26
