Question

Can yall plz help me answer this!!!

Answer 1

d=1

Explanation:

distribute 0.5 through the parentheses

3.5d+2=7-1.5d

move variable to the left-hand side and change its sign

3.5d+1.5d+2=7

move constant to the right-hand side and change its sign

3.5d+1.5d=7-2

collect all like terms

5d=7-2

subtract the numbers

5d=5

divide both sides

d=1
