Step-by-step explanation:
Step 1: Distribute
4 (x - 3) = 2x + 7
4x - 12 = 2x + 7
Step 2: Add 12 to both sides
4x - 12 + 12 = 2x + 7 + 12
4x = 2x + 19
Step 3: Subtract 2x from both sides
4x - 2x = 2x + 19 - 2x
2x = 19
Step 4: Divide both sides by 2
2x / 2 = 19 / 2
x = 9.5
Step 5: Plug in 9.5 for x into 4x - 3
4x - 3
4 (9.5) - 3
38 - 3

Let's start by solving this equation using distribution method:
4 (x - 3) = 2x + 7
4x - 12 = 2x + 7.
Move like terms on one side:
4x - 2x = 7 + 12
2x = 19
x = 9.5
Let's plug in x for 4x-3:
4x - 3
4 * 9.5 - 3
38 - 3
35
4x - 3 = 35
