The some of the numbers is 77. the greater number is 5 more than the smaller number. which equation can be used to solve for the smaller number?

Let the smaller number be x and the larger one be y

x + y = 77

y = x + 5

Substituting into the first equation

x + (x + 5) = 77

2x + 5 = 77

Subtracting 5 to both sides

2x +5 -5 = 77-5

2x = 72

Divide both sides by 2

2x/2 = 72/2

x = 36

a.

step-by-step explanation:

step 1 distribute 2 to every term in the parentheses

step 2 add 10 on both sides of the equal sign

x equals 1
