# Appendix B - Exercise Set: 3

$x=6$

#### Work Step by Step

$5x-4=26$ Step 1: is not needed since there are no fractions. Step 2: is not needed since there are no parentheses. Step 3: is not needed. Step 4: the equation is linear. Step 5: $5x-4+4=26+4$ (Add 4 to both sides) $5x=30$ Step 6:$\frac{5x}{5}=\frac{30}{5}$ Divide both sides by 5. x=6 Final Step: check: $5\times6=30$
