Hey there!
2(x + 3) = 16
☆ Distribute ↪ The formula is: : a (b + c) = a(b) + a(c) = ab + ac
➡ ➡ 2(x + 3) = 2(x) + 2(3) = 2x + 6
☆ New equation: 2x + 6 = 16
☆Subtract by 6 on your sides
2x + 6 - 6 = 16 - 6
☆ Cancel out: 6 - 6 because it equals 0
☆ Keep: 16 - 6 because it equals 10 and that helps us solve for your equation
☆ New equation: 2x = 10
☆ Divide by 2 on your sides
2x/2 = 10/2
☆ Cancel out: 2x / 2 because that gives you 1
☆ Keep: 10/2 because it gives you x
☆☆ 10/2 = x ; 10 ÷ 2 = 5☆☆
∴ Your answer is: x = 5 ✅
Good luck on your assignment and enjoy your day!
