h = 63

Multiply both sides of the equation by 7.

36

63

Set up the equation and solve: 13 = 7 + s (next subtract 7 from each side of the equation to solve for s) 6 = s

h = 16 16-9 = 7

It is not possible to solve a single linear equation in two variables.

6

You cannot solve one linear equation in two unknown variables.

7

You can't solve it - you only have one equation and two unknowns. You need 2 equations to solve this.

The answer to 9 times 7 equals 63. This is taught in math class.

7x=42 x=42/7 or, x=6

4y + 7 = 19 ∴ 4y = 12 ∴ y = 3

7x = 42 so x = 42/7 and therefore x = 6

4x-7=24x=9 x=9/4

19-2t = 7 -2t = 7-19 -2t = -12 t = 6

3h+13 = 7 3h = 7-13 3h = -6 h = -2

Set up the equation and solve: 7y - 7 = -105 (next add 7 to each side of the equation) 7y = -98 (next divide both sides by 7 to solve for y) y = -14 (solution)

First, subtract 3x from each side of the equation. Then, divide each side of the equation by 7 .

To solve the equation 5n - 7 = 38, do whatever you do to one side of the equals sign to the other. So, add 7 to both sides. 5n = 38. Now divide both sides by 9. 5 = 9. To check your answer, replace the n with 9 and solve the equation. 5 x 9 - 7 = 38. Do the multiplacation first. 45 - 7 = 38. 38 = 38. The answer is correct.

Slope for the equation y equals 7 is zero.

h/9=7 multiply both sides by 9 h=63

h/(-3 - 7) = 10h/-10 = 10h = -100
