Solution for 2[m-(4m+15)+7]=2(m+8) equation:


Simplifying
2[m + -1(4m + 15) + 7] = 2(m + 8)

Reorder the terms:
2[m + -1(15 + 4m) + 7] = 2(m + 8)
2[m + (15 * -1 + 4m * -1) + 7] = 2(m + 8)
2[m + (-15 + -4m) + 7] = 2(m + 8)

Reorder the terms:
2[-15 + 7 + m + -4m] = 2(m + 8)

Combine like terms: -15 + 7 = -8
2[-8 + m + -4m] = 2(m + 8)

Combine like terms: m + -4m = -3m
2[-8 + -3m] = 2(m + 8)
[-8 * 2 + -3m * 2] = 2(m + 8)
[-16 + -6m] = 2(m + 8)
