Answer:
x = 8
Step-by-step explanation:
5( 8 + 7 ) = 5 ⋅ x + 5 ⋅ 7
Add 8 and 7 to get 15.
5 × 15 = 5x + 5 × 7
Multiply 5 and 15 to get 75.
75 = 5x + 5 × 7
Multiply 5 and 7 to get 35.
75 = 5x + 35
Swap sides so that all variable terms are on the left-hand side.
5x + 35 = 75
Subtract 35 from both sides.
5x = 75 − 35
Subtract 35 from 75 to get 40.
5x = 40
Divide both sides by 5.
x =
Divide 40 by 5 to get 8.
x = 8
