Answer 1

Answer/Explanation:

We would solve for the value of x in each case.

1.
`4x = 12`

`x = (12)/(4)` (division property of equality)

`x = 3`

2.
`(x)/(14) = -7`

`x = -7 * 14` (multiplication property of equality)

`x = -98`

3.
`26 = 14 + x`

`26 - 14 = x` (subtraction property of equality)

`12 = x`

`x = 12`

4.
`-2 + x = 7`

`x = 7 + 2` (addition property of equality)

`x = 9`

5.
`x - 6 = -2`

`x = -2 + 6` (addition property of equality)

`x = 4`

6.
`- 5 = (x)/(8)`

`- 5 * 8 = x` (multiplication property of equality)

`-40 = x`

7.
`- 7 = x + 3`

`- 7 - 3 = x` (subtraction property of equality)

`-10 = x`

`x = -10`

8.
`-6x = 42`

`x = (42)/(-6)` (division property of equality)

`x = -7`

9.
`(x)/(6) = 4`

`x = 4 * 6` (multiplication property of equality)

`x = 24`

10.
`13 = x - 4`

`13 + 4 = x` (addition property of equality)

`17 = x`

`x = 17`

11.
`100 = -25x`

`(100)/(-25) = x` (division property of equality)

`-4 = x`

`x = -4`

12.
`-7 + x = 4`

`x = 4 + 7` (subtraction property of equality)

`x = 11`

13.
`7 + x = 37`

`x = 37 - 7` (subtraction property of equality)

`x = 30`

14.
`56 = 8x`

`(56)/(8) = x` (division property of equality)

`7 = x`

`x = 7`

15.
`(x)/(1) = -18`

`x = -18` (multiplication property of equality)

`x = -18`

16.
`x + 6 = 16`

`x = 16 - 6` (subtraction property of equality)

`x = 10`

17.
`x - 1 = -1`

`x = -1 + 1` (subtraction property of equality)

`x = 0`

18.
`10x = 70`

`x = (70)/(10)` (division property of equality)

`x = 7`

19.
`-11 = (x)/(3)`

`-11 * 3 = x` (multiplication property of equality)

`x = -33`

20.
`x - 5 = 1`

`x = 1 + 5` (addition property of equality)

`x = 6`
