63
It is not possible to solve a single linear equation in two variables.
h = 63
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
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.
if the equation was 7x = 42. The answer would be x = 6
