-3(5 + -1d) = 2d + 10
simplify the expression inside the parentheses
-3(5 - d) = 2d + 10
now remove the parentheses
-15 + 3d = 2d + 10
add 15 to both sides of the equation
3d = 2d + 25
subtract 2d from both sides of the equation
d = 25
To double check, substitute 25 for d in the original equation:
-3(5 + -1(25)) = 2(25) + 10
-3(5 - 25) = 2(25) + 10
-3(-20) = 2(25) + 10
60 = 50 + 10
