slove and check 2.5x-13=2
Solve2.5x-13=2Add 13 to both sides2.5x=15Divide 2.5 on both sidesFinal Answer: x= 6Check2.5x-13=2Substitue 6 for x2.5(6)-13=2Multiply 2.5 by 615-13=2Add 13 to both sidesFinal Answer: 15=15 This proves that the x value(6) is true
that's basically it, it shows the simple way of solve it and to check it you apply the 6 to all the x's in the equation.
