design five equations, like 3x + 4 = 16. make sure that the solutions to the equations are integers. in other words, 3x + 4 = 15 wouldn't be acceptable, because the solution would be x = 11/3.

Step-by-step explanation:

Easiest

Arrange the arithmetic expression. Calculate its value. Exchange one number to "x".

2 + 12 - 6(2) = 14 - 12 = 2

x + 12 - 6x = 2   (x = 2)

3(5 + 2) + 2(5) = 3(7) + 10 = 21 + 10 = 31

3(x + 2) + 2x = 31     (x = 5)

(11 + 4) : 3 - 2(4) = 15 : 3 - 8 = 5 - 8 = -3

(11 + x) : 3 - 2x = -3           (x = 4)

4(0) + 3(7 + 0) - 5 = 0 + 3(7) - 5 = 21 - 5 = 16

4x + 3(7 + x) - 5 = 16     (x = 0)

2(1) - 3(1 + 4) + 8 = 2 - 3(5) + 8 = 2 - 15 + 8 = -5

2x - 3(x + 4) + 8 = -5        (x = 1)

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
