Solution for 4(r-4)-3(r-1)=2(r+6) equation:


Simplifying
4(r + -4) + -3(r + -1) = 2(r + 6)

Reorder the terms:
4(-4 + r) + -3(r + -1) = 2(r + 6)
(-4 * 4 + r * 4) + -3(r + -1) = 2(r + 6)
(-16 + 4r) + -3(r + -1) = 2(r + 6)

Reorder the terms:
-16 + 4r + -3(-1 + r) = 2(r + 6)
-16 + 4r + (-1 * -3 + r * -3) = 2(r + 6)
-16 + 4r + (3 + -3r) = 2(r + 6)

Reorder the terms:
-16 + 3 + 4r + -3r = 2(r + 6)

Combine like terms: -16 + 3 = -13
-13 + 4r + -3r = 2(r + 6)
