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
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
