Step-by-step explanation:

Step 1: Define

35 + 0.8x = 43 - 7x

Step 2: Solve for x

1. [Addition Property of Equality] Add 7x on both sides:                                 35 + 7.8x = 43
2. [Subtraction Property of Equality] Subtract 35 on both sides:                    7.8x = 8
3. [Division Property of Equality] Divide 7.8 on both sides:                             x = 1.02564
