Solution for 3[w-(10-w)]=7(w+1) equation:


Simplifying
3[w + -1(10 + -1w)] = 7(w + 1)
3[w + (10 * -1 + -1w * -1)] = 7(w + 1)
3[w + (-10 + 1w)] = 7(w + 1)

Reorder the terms:
3[-10 + w + 1w] = 7(w + 1)

Combine like terms: w + 1w = 2w
3[-10 + 2w] = 7(w + 1)
[-10 * 3 + 2w * 3] = 7(w + 1)
[-30 + 6w] = 7(w + 1)

Reorder the terms:
-30 + 6w = 7(1 + w)
-30 + 6w = (1 * 7 + w * 7)
-30 + 6w = (7 + 7w)

Solving
-30 + 6w = 7 + 7w

Solving for variable 'w'.

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

Add '-7w' to each side of the equation.
-30 + 6w + -7w = 7 + 7w + -7w

Combine like terms: 6w + -7w = -1w
-30 + -1w = 7 + 7w + -7w

Combine like terms: 7w + -7w = 0
-30 + -1w = 7 + 0
-30 + -1w = 7

Add '30' to each side of the equation.
-30 + 30 + -1w = 7 + 30

Combine like terms: -30 + 30 = 0
0 + -1w = 7 + 30
-1w = 7 + 30

Combine like terms: 7 + 30 = 37
-1w = 37

Divide each side by '-1'.
w = -37

Simplifying
w = -37
