Chapter 9 - Basic Algebra - 9.7 Solving Equations with Several Steps - 9.7 Exercises: 56

Answer

$x=1$

Work Step by Step

Step 1. Add 3x to both sides of the equation. $5x+3x-4=-3x+3x+4$ $8x-4=4$ Step 2. Add 4 to both sides. $8x-4+4=4+4$ $8x=8$ Step 3. Divide both sides by 8. $\frac{8x}{8}=\frac{8}{8}$ $x=1$
