Answer:

X = 3  , Y = 1

Step-by-step explanation:

Given equations are

Y = X - 2    ........  A

Y = -2X + 7     .....B

Put the value of Y from eq A to the eq B

∴ X - 2 = -2X + 7

Or, X + 2X = 7 + 2

Or, 3X = 9

Or, X = [tex]\frac{9}{3}[/tex]

∴ X = 3

Now to get the value of Y , put X value in any of above two Eq.

pu X value in Eq A

We get Y = X - 2

so, Y = 3-2

Y= 1

Hence  X = 3 and Y = 1   Answer
