63
h/9=7 multiply both sides by 9 h=63
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.
7
h = 63
4x-7=24x=9 x=9/4
x 4HowThe starting equation is: 4x - 9 7To solve, first add 9 to both sides:4x 16Now, divide both sides by 4:x 4
Which of the following equations could be used to solve for the tenth term of the following sequence?15, 13, 11, 9, ...
I assume you have : 5x - 9 = 3x + 11This is a single algebraic expression.Subtract 3x from both sides.5x - 9 - 3x = 3x + 11 - 3x2x - 9 = 11Add 9 to both sides :2x - 9 + 9 = 11 + 92x = 20x = 10
9
7
Well, first you add 7 to 38, which is 45, then divide by 5, therefore n=9.
