Answer:
x = 5
Explanation:
8x + 7 = 2x + 37 Subtract 2x from both sides of the equation
6x + 7 = 37 Subtract 7 from both sides
6x = 30 Divide both sides by 6
x = 5
Or you could plug in 5 for x and solve. If the equation is true, that is the answer
x= 5
8x + 7 = 2x + 37
8(5) + 7 = 2(5) + 37
40 + 7 = 10 + 37
47 = 47
If you try this with any other number, it will not equal. Lets try x = 11
8x + 7 = 2x + 37
8(11) + 7 = 2(11) + 37
88 + 7 = 22 + 37
95 ≠ 59 so x does not equal 11
