<h2><u><em>
x = -7</em></u></h2>
Step-by-step explanation:
_3x_13 =_7x+15 what is the anSWER?
assuming that the underscore is a minus and you are looking for the x value.
-3x - 13 = -7 + 15
-3x = -7 + 15 + 13
-3x = 8 + 13
-3x = 21
x = -7

check
-3 * (-7) - 13 = -7 + 15
21 - 13 = 8
8 = 8
<u><em>the answer is good</em></u>
Find cost of shoes first (7.50)
subtract from the total value (55.20-7.50= 47.7)
