Question

The difference of two number is 7 and their sum is 53. Find the numbers​

Answer 1

Answer:

We are given:

a + b = 53

a / b = 7

If so then:

a = 7 * b

through multiplying both sides by b to isolate a

Now back to our original equation we can substitute this in for a and solve:

(7 * b) + b = 53

7b + 1b = 53

8b = 53

b = 53/8 + 6.625

Now that we know b, we can solve for a

a = 7 * 6.625 = 46.375

Answer 2

Answer:

x=30, y =23

Step-by-step explanation:

x - y = 7

x + y = 53

by elimination method,

x+x -y+y =7+53

2x + 0 = 60

x = 30

by substitution method,

x-y =7

(30) -y =7

-y = 7-30

-y =-23

y =23
