Question

4x - 2y =7
X +2y =3
What is x and y ??

Answer 1

Answer:

x=2. y=1/2

Step-by-step explanation:

4x-2y=7. Equation 1

x+2y=3. Equation 2

Add the two equations

(4x+x) +(-2y+2y) =7+3

5x+0=10

5x=10 divide both sides by 5

X=2

Substitute x=2 in equation 2

2+2y=3

2y=3-2

2y=1. Divide both side by 2

Y=1/2
