There are m any examples of equations that equal 31. Here are a few:
17 + 14
30 + 1
60 - 29
I like this one though (its 2 step)
(15 x 2) + 1
Hope this helped :)
8x - 2y = 48, y =4
8x - 2(4) = 48
8x - 8 = 48
8x = 48+8
8x = 56
x = 56/8 = 7
x = 7
2(x-5)=20
Divide both sides by 2 (division of property equality)
x - 5 = 10
Add 5 to both sides (addition of property equality)
x = 15
Answer
x = 15 is the solution
