Question

Solve the following system of equations. 2x+y=3 x=2y-1

Answer 1

Answer:

( 1 , 1 )

Step-by-step explanation:

2x + y = 3

x = 2y - 1

(You already have x so substitute x back into 2x + y = 3)

2(2y - 1) + y = 3

4y - 2 + y = 3

5y - 2 = 3

(Add -2 to both sides)

5y = 5

(Divide each side by 5 to isolate x)

y = 1

(Plug y into x = 2y - 1 to find x)

x = 2(1) - 1

x = 2 - 1

x = 1
