Start from the inside and work outward.

5 - 3(6x - 8 + 3) = 5 - 18x + 5 = -18x

2. (3x^2 - 4y^2)/(4x -7y) Just plug in the numbers and calculate. (x^2 = x squared online.)

3. Multiply both sides by -4/3.

4. From the way you express the equation, I don't know which numbers belong where.

(m + 1)/4 + 5/6 = (2m - 1)/12?
