answer:To solve for x in "4x + 7 = 31 and 2x - 8 = 12", we can follow these steps: 1. For the first equation, subtract 7 from both sides: 4x + 7 - 7 = 31 - 7 4x = 24 2. Divide both sides by 4 to isolate x: 4x/4 = 24/4 x = 6 3. For the second equation, add 8 to both sides: 2x - 8 + 8 = 12 + 8 2x = 20 4. Divide both sides by 2 to isolate x: 2x/2 = 20/2 x = 10 Therefore, the solution to "4x + 7 = 31 and 2x - 8 = 12" is x = 6 and x = 10.
