There are a few steps you have to follow when you have an equation with brackets. So let’s break this down!
Solve the equation:
Expand the brackets: 3x + 12 = 27
Subtract 12 from both sides: 3x + 12 – 12 = 27 – 12
Simplify: 3x = 15
Divide by three: 3x ÷ 3 = 15 ÷ 3
Simplyfy: x = 5
Every equation is not the same, therefore the steps will be different for each.
