Question

I don’t know how to solve this problem

Answer 1

x = 5, y = 25

Explanation:

I use the substitution method to solve. (I hope I got the equations correct)

6x + y = 55 ---1

10x + 3y = 125 ---2

From 1: y = 55 - 6x ---3

Substitute 3 into 2:

10x + 3(55 - 6x) = 125

10x + 165 - 18x = 125

- 8x = - 40

x = 5

Substitute x into 3

y = 55 - 6(5) = 25
