Question

What is the solution for the following system of equations?

5x + 7y = 3

2x + 3y = 1

Answer 1

A) 5x + 7y = 3
B) 2x + 3y = 1

Multiplying Equation B by -2.5
B) -5x -7.5y = -2.5 Then adding this to Equation A)
A) 5x + 7y = 3

-.5y  = .5
y = -1

Since
2x + 3y = 1 then
2x -3 = 1
then x = 2
