Solve the following.

never [62]

Answer:

b. x = 11/8, x = 59/72.

Step-by-step explanation:

4|8x - 6| = 5|-8x + 7|

square both sides:

16(64x^2 - 96x + 36) = 25( 64x^2 - 112x + 49)

1600x^2 - 1024x^2 - 2800x + 1536x + 1225 - 576 = 0

576x^2 - 1264x + 649 = 0

x = [1264 +/- √(1264^2 - 4 * 576* 649)] / (2*576)

x = 11/8, x = 59/72.
