Exercise 40 Page 36

Gather all of the variable terms on one side of the equation and all of the constant terms on the other side.

No solution

Practice makes perfect

To solve an equation, we should first gather all of the variable terms on one side of the equation and all of the constant terms on the other side, using the Properties of Equality. In this case, we will start by subtracting x from both sides of the equation.

x+4=x-12

LHS-x=RHS-x

x+4-x=x-12-x

Subtract terms

4≠- 12

Simplifying the equation resulted in a contradiction. Thus, the equation has no solution.
