Solution for 12-3(2w+1)=10w-3(10+w) equation:


Simplifying
12 + -3(2w + 1) = 10w + -3(10 + w)

Reorder the terms:
12 + -3(1 + 2w) = 10w + -3(10 + w)
12 + (1 * -3 + 2w * -3) = 10w + -3(10 + w)
12 + (-3 + -6w) = 10w + -3(10 + w)

Combine like terms: 12 + -3 = 9
9 + -6w = 10w + -3(10 + w)
9 + -6w = 10w + (10 * -3 + w * -3)
9 + -6w = 10w + (-30 + -3w)

Reorder the terms:
9 + -6w = -30 + 10w + -3w
