Answer: 12a+ 13b
Step-by-step explanation:
Divide 7 by 5 as if it is a normal number without the decimal. When you get the final answer, put the decimal two values over
A qt and a half i believe.
(x + 1) / 5 = (x + 5) / 7
cross multiply
(x +1) x 7 = 5 x (x + 5)
7x + 7 = 5x + 25
take the like terms to one side
7x - 5x = 25 - 7
2x = 18
divide by 2 to isolate x
2x / 2 = 18 / 2
x = 9
check:
9 + 1 / 5 = 9 + 5 / 7
10 / 5 = 14 / 7
2 = 2
