2/3 (7/8 - 4x) - 5/8 = 3/8
multiply 2/3 by 7/8 - 4x
2/3 x 7/8 = 7/12
2/3 x -4x = -8/3x
7/12 - 8/3x - 5/8
-1/24 - 8/3x = 3/8
add -1/24 to both sides
-8/3x = 3/8 + 1/24
-8/3x = 5/12
x = 5/12 / -8/3
x = -15/96 or
answer: x = -5/32
multiply 2/3 by 7/8 - 4x
2/3 x 7/8 = 7/12
2/3 x -4x = -8/3x
7/12 - 8/3x - 5/8
-1/24 - 8/3x = 3/8
add -1/24 to both sides
-8/3x = 3/8 + 1/24
-8/3x = 5/12
x = 5/12 / -8/3
x = -15/96 or
answer: x = -5/32
