Question

Do the first step of solving this equation by substitution, by creating a single equation (do not use spaces)

Answer 1

x= 1 y= 3

Explanation:

y= 2x+1

y= 4x-1

4x-1=2x +1

4x-2x= 1+1

2x=2

x=2/2

x=1. replace x=1 in any of the equation to find y

y= 2(1)+1

y= 2+1

y=3

Answer 2

x=1 y=3
