Solution for 7(r-4)-6(r-1)=2(r+6) equation:


Simplifying
7(r + -4) + -6(r + -1) = 2(r + 6)

Reorder the terms:
7(-4 + r) + -6(r + -1) = 2(r + 6)
(-4 * 7 + r * 7) + -6(r + -1) = 2(r + 6)
(-28 + 7r) + -6(r + -1) = 2(r + 6)

Reorder the terms:
-28 + 7r + -6(-1 + r) = 2(r + 6)
-28 + 7r + (-1 * -6 + r * -6) = 2(r + 6)
-28 + 7r + (6 + -6r) = 2(r + 6)

Reorder the terms:
-28 + 6 + 7r + -6r = 2(r + 6)

Combine like terms: -28 + 6 = -22
-22 + 7r + -6r = 2(r + 6)
