Equality Properties

Step-by-step explanation:

Step 1: Define

7x + 10 = 1/3(12x - 3) + 14x

Step 2: Solve for x

Distribute 1/3:                              7x + 10 = 4x - 1 + 14xCombine like terms:                   7x + 10 = 18x - 1Subtract 7x on both sides:         10 = 11x - 1Add 1 on both sides:                   11 = 11xDivide 11 on both sides:              1 = xRewrite:                                        x = 1
