2(4-7)=7u+2-2(-5u-1)

Solution for 2(4-7)=7u+2-2(-5u-1) equation:

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

Combine like terms: 4 + -7 = -3
2(-3) = 7u + 2 + -2(-5u + -1)

Multiply 2 * -3
-6 = 7u + 2 + -2(-5u + -1)

Reorder the terms:
-6 = 7u + 2 + -2(-1 + -5u)
-6 = 7u + 2 + (-1 * -2 + -5u * -2)
-6 = 7u + 2 + (2 + 10u)

Reorder the terms:
-6 = 2 + 2 + 7u + 10u

Combine like terms: 2 + 2 = 4
-6 = 4 + 7u + 10u

Combine like terms: 7u + 10u = 17u
-6 = 4 + 17u

Solving
-6 = 4 + 17u

Solving for variable 'u'.

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

Add '-17u' to each side of the equation.
-6 + -17u = 4 + 17u + -17u

Combine like terms: 17u + -17u = 0
-6 + -17u = 4 + 0
-6 + -17u = 4

Add '6' to each side of the equation.
-6 + 6 + -17u = 4 + 6

Combine like terms: -6 + 6 = 0
0 + -17u = 4 + 6
-17u = 4 + 6

Combine like terms: 4 + 6 = 10
-17u = 10

Divide each side by '-17'.
u = -0.5882352941

Simplifying
u = -0.5882352941
