Algebra 1 Section 3.4 Solve equations with variables on both sides of the equation. Solve: 17 – 2x = x Solve 80 – 9y = 6y

To solve a linear equation. 1.Simplify both sides. 2.Isolate the variable terms from the constants. 3.Eliminate the coefficients of the variable term. 2(5x + 4) = 6x + 4

Solve 4(x – 5) = 4x - 206(x – 4) = 3(2x + 5) 7x + 4(3 – 2x) = 5 + 3(x + 8)

solve ½ (12 – 2x) – 4 = 5x + 2(x-7)-(8n – 2) = 7 – 2(3 – 5n)
