Solution for 7(x-8)-8(x-z)=x+7-(x-3) equation:


Simplifying
7(x + -8) + -8(x + -1z) = x + 7 + -1(x + -3)

Reorder the terms:
7(-8 + x) + -8(x + -1z) = x + 7 + -1(x + -3)
(-8 * 7 + x * 7) + -8(x + -1z) = x + 7 + -1(x + -3)
(-56 + 7x) + -8(x + -1z) = x + 7 + -1(x + -3)
-56 + 7x + (x * -8 + -1z * -8) = x + 7 + -1(x + -3)
-56 + 7x + (-8x + 8z) = x + 7 + -1(x + -3)

Combine like terms: 7x + -8x = -1x
-56 + -1x + 8z = x + 7 + -1(x + -3)

Reorder the terms:
-56 + -1x + 8z = x + 7 + -1(-3 + x)
-56 + -1x + 8z = x + 7 + (-3 * -1 + x * -1)
-56 + -1x + 8z = x + 7 + (3 + -1x)

Reorder the terms:
-56 + -1x + 8z = 7 + 3 + x + -1x

Combine like terms: 7 + 3 = 10
-56 + -1x + 8z = 10 + x + -1x

Combine like terms: x + -1x = 0
-56 + -1x + 8z = 10 + 0
-56 + -1x + 8z = 10

Solving
-56 + -1x + 8z = 10

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.
