Solution for u=4(u-z)+7+5(2u-3) equation:


Simplifying
u = 4(u + -1z) + 7 + 5(2u + -3)
u = (u * 4 + -1z * 4) + 7 + 5(2u + -3)
u = (4u + -4z) + 7 + 5(2u + -3)

Reorder the terms:
u = 4u + -4z + 7 + 5(-3 + 2u)
u = 4u + -4z + 7 + (-3 * 5 + 2u * 5)
u = 4u + -4z + 7 + (-15 + 10u)

Reorder the terms:
u = 7 + -15 + 4u + 10u + -4z

Combine like terms: 7 + -15 = -8
u = -8 + 4u + 10u + -4z

Combine like terms: 4u + 10u = 14u
u = -8 + 14u + -4z

Solving
u = -8 + 14u + -4z

Solving for variable 'u'.

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

Add '-14u' to each side of the equation.
u + -14u = -8 + 14u + -14u + -4z

Combine like terms: u + -14u = -13u
-13u = -8 + 14u + -14u + -4z

Combine like terms: 14u + -14u = 0
-13u = -8 + 0 + -4z
-13u = -8 + -4z

Divide each side by '-13'.
u = 0.6153846154 + 0.3076923077z

Simplifying
u = 0.6153846154 + 0.3076923077z
