Question

Solve the following equation for d. 2(7d+2) +5d =156 A.10 B.2 C.8 D.4

Answer 1

Plze mark me brainiest:

Let's solve your equation step-by-step.

2(7d+2)+5d=156

Step 1: Simplify both sides of the equation.

2(7d+2)+5d=156

(2)(7d)+(2)(2)+5d=156(Distribute)

14d+4+5d=156

(14d+5d)+(4)=156(Combine Like Terms)

19d+4=156

19d+4=156

Step 2: Subtract 4 from both sides.

19d+4−4=156−4

19d=152

Step 3: Divide both sides by 19.

19d

19

152

19

d=8

Answer:

d=8

Answer 2

Answer:

C. 8

Step-by-step explanation:

First distribute (multiply) the 2 to the 7d and 2

14d + 4 + 5d = 156

Then combine like terms ( add 14d and 5d)

19d + 4 = 156

Subtract 4 from 156

19d = 152

Divide 152 by 19

d = 8
