Question

An equation is shown below:

4(3d - 7) = -52


Part A: How many solutions does this equation have? (4 points)


Part B: Solve this equation showing your work (at least three steps). (6 points)

Answer 1

Part A: 1 solution


Part B:
4(3d −7) = −52

(4)(3d) + (4)(-7)= -52

12d + -28 = -52

12d - 28 = -52

12d - 28 + 28 = -52 + 28

12d = -24

12d/12 = -24/12

d = -2
