1.) Distribute the 3: 3(x +1)=15 ---> 3x+3=15 2.) Subtract 3 from both sides, first step in isolating x: 3x+3=15 ---> 3x=12 3.) Divide both sides by 3, isolating x: 3x=12 ---> x=4 x=4

3(x + 1) = 15 3x + 3 = 15 ∴ 3x = 15 - 3 ∴ 3x = 12 ∴ x = 12/3 ∴ x = 4

Divide both sides by 3 and get: x+1 = 5 subtract 1 from both sides and get x=4

Multiply the three out. You get 3x + 3 = 15. Subtract three from both sides. You get 3x = 12 Then divide by 3. You get x = 4.

x = 4. Divide both sides by 3, then subtract 1 from both sides. There's x.
