Solution for 2[m+3(2m-3)]=6(m-7) equation:


Simplifying
2[m + 3(2m + -3)] = 6(m + -7)

Reorder the terms:
2[m + 3(-3 + 2m)] = 6(m + -7)
2[m + (-3 * 3 + 2m * 3)] = 6(m + -7)
2[m + (-9 + 6m)] = 6(m + -7)

Reorder the terms:
2[-9 + m + 6m] = 6(m + -7)

Combine like terms: m + 6m = 7m
2[-9 + 7m] = 6(m + -7)
[-9 * 2 + 7m * 2] = 6(m + -7)
[-18 + 14m] = 6(m + -7)

Reorder the terms:
-18 + 14m = 6(-7 + m)
-18 + 14m = (-7 * 6 + m * 6)
-18 + 14m = (-42 + 6m)

Solving
-18 + 14m = -42 + 6m

Solving for variable 'm'.
