Work Step by Step

$2y-3=11$ 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: $2y-3+3=11+3$ (Add 3 to both sides) $2y=14$ Step 6:$\frac{2y}{2}=\frac{14}{2}$ Divide both sides by 2. $y=7$ Final Step: check: $2\times7-3=11$
