Solving Equations of the Form px + q = r — 7th Grade

1. If a number is represented by x, then the equation 3x + 5 = 20 can be solved for x. Thus, _____ = x.
2. To solve the equation 2x - 4 = 10, first add 4 to both sides. Thus, _____ = 14.
3. In the equation 5(x + 2) = 25, you first divide by 5. Thus, _____ = x + 2.
4. To find x in the equation 4x + 6 = 30, we first subtract 6. Thus, _____ = 24.
5. The equation 7x = 42 can be solved by dividing both sides by 7. Therefore, _____ = x.
6. If the equation is 10x + 15 = 75, after subtracting 15 we get 10x = _____.
7. In the equation p(x + 3) = 24, if p = 4, then _____ is the equation to solve for x.
8. When solving 3x - 2 = 16, we can compare the arithmetic solution. Thus, _____ = 18.
9. In the word problem, if 5 more than twice a number x equals 25, we write: 2x + 5 = _____.
10. To solve the equation 6(x - 1) = 30, we first divide by 6, resulting in _____ = x - 1.
11. If a number decreased by 7 equals 12, we write the equation x - 7 = _____.
12. To find the value of x in the equation 8 + 4x = 36, we first subtract 8. Thus, _____ = 4x.
