Question

Solve equation 13=x/7+5

Answer 1

(7) X/7+5=13 (7) multipl 7 to cancel the division

49x+5= 91
-5. -5. Subtract 5 to get X by itself

49x = 86
—————
49. 49. Divide number with X to 86

X = 1.76 if round to the hundredth solution

Answer 2

56

Explanation:

Isolate the variable (x). Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

First, subtract 5 from both sides:

13 (-5) = (x/7) + 5 (-5)

13 - 5 = x/7

8 = x/7

Isolate the variable x. Multiply 7 to both sides:

8(7) = (x/7)(7)

8(7) = x

x = 8 * 7

x = 56

56 is your answer for x.
