4. Solving Equations With Variables on Both Sides

Continue to next subchapter

Exercise 4 Page 105

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 and all of the constant terms on the other side using the Properties of Equality. In this case, we need to start by using the Distributive Property to simplify the right-hand side of the equation.

4x-5=2(2x+1)

Distribute 2

4x-5=4x+2

We continue to simplify using the Properties of Equality.

4x-5=4x+2

LHS-4x=RHS-4x

4x-5-4x=4x+2-4x

Subtract terms

- 5 = 2 *

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