Question 412829
"One number is 4 more than another number. Find the two numbers if two times the larger number is 7 less than five times the smaller number."


x = one number
x + 4 = other number


2(x + 4) = 5x - 7 {two times larger is seven less than 5 times smaller}
2x + 8 = 5x - 7 {used distributive property}
2x = 5x - 15 {subtracted 8 from both sides}
-3x = -15 {subtracted 5x from both sides}
x = 5 {divided both sides by -3}
x + 4 = 9 {substituted 5, in for x, into x + 4} 


The two numbers are 5 and 9.
