Sarita showed the steps to solving the equation. 5 (x minus 3) + 7 (x + 4) = 73
Steps
Sarita’s Solution
Sarita’s Verification
1
5 x minus 15 + 7 x + 28 = 73
5 (5 minus 3) + 7 (5 + 4) = 73. 5 (negative 2) + 7 (9) = 73. Negative 10 + 63 = 73. 53 not-equal-to 73.
2
(5 + 7) x + (negative 15 + 28) = 73
3
12 x + 13 = 73
4
12 x + 60
5
x = 5
