Solve for x: 3x - 7 = 2x + 5
Answer: x = 12
Subtract 2x from both sides to get x - 7 = 5, then add 7 to get x = 12.
Which value of x satisfies the inequality 4x + 1 > 13?
Answer: x = 4
Solving 4x > 12 gives x > 3, so x = 4 is the only choice greater than 3.
What is the solution to 2(x + 3) = 14?
Answer: x = 4
Distribute to get 2x + 6 = 14, subtract 6 to get 2x = 8, then divide by 2 to get x = 4.
Solve the equation: x/5 = 9
Answer: x = 45
Multiply both sides by 5 to get x = 45.
Which inequality represents 'five less than twice a number is at most 11'?
Answer: 2n - 5 ≤ 11
'Twice a number' is 2n and 'five less than' means subtract 5, giving 2n - 5 ≤ 11.
If 5y = 35, what is the value of y + 3?
Answer: 10
Dividing 35 by 5 gives y = 7, and 7 + 3 = 10.
Solve for x: -3x ≤ 12
Answer: x ≥ -4
Dividing both sides by -3 requires flipping the inequality sign, giving x ≥ -4.
