Solve: 7x + 5 = 6x + 2.
Ax=-3
Bx=3
Cx=-7
Dx=7
Answer & Solution
Correct answer: A. x=-3
1. Choose the left side as the variable side, so subtract 6x from both sides: x plus 5 equals 2.
2. Subtract 5 from both sides: x equals -3.
3. Check: 7 times -3, plus 5, equals -16, and 6 times -3, plus 2, also equals -16.
