Problem
Solve: 2x + 3 = 11
Step-by-Step Solution
Step 1: Subtract 3 from both sides: 2x = 8
Step 2: Divide both sides by 2: x = 4
Answer
x = 4
Problem
Solve: 5x − 7 = 18
Step-by-Step Solution
Step 1: Add 7 to both sides: 5x = 25
Step 2: Divide both sides by 5: x = 5
Answer
x = 5
Problem
Solve: x/3 + 4 = 10
Step-by-Step Solution
Step 1: Subtract 4 from both sides: x/3 = 6
Step 2: Multiply both sides by 3: x = 18
Answer
x = 18
Problem
Solve: −3x + 1 = 13
Step-by-Step Solution
Step 1: Subtract 1 from both sides: −3x = 12
Step 2: Divide both sides by −3: x = −4
Answer
x = −4
Problem
Solve: x/5 − 2 = 3
Step-by-Step Solution
Step 1: Add 2 to both sides: x/5 = 5
Step 2: Multiply both sides by 5: x = 25
Answer
x = 25
