Solve for x: 4(x - 1) = 2x + 6.
Answer: 5
Distribute to get 4x - 4 = 2x + 6, so 2x = 10 and x = 5.
A number increased by 8 equals 23. What is the number?
Answer: 15
Let n + 8 = 23, so n = 15.
Solve for x: 6x - 3 = 2x + 13.
Answer: 4
Subtract 2x and add 3 to get 4x = 16, so x = 4.
Simplify: 5x - (2x + 7).
Answer: 3x - 7
Distribute the negative to get 5x - 2x - 7 = 3x - 7.
Solve the inequality: 2x - 4 > 6.
Answer: x > 5
Add 4 to get 2x > 10, then divide by 2 to get x > 5.
If y = 2x + 1, what is y when x = 6?
Answer: 13
y = 2(6) + 1 = 12 + 1 = 13.
Solve for x: 9 - x = 2.
Answer: 7
Subtract 9 to get -x = -7, so x = 7.
