Question

X-2.6y=-3.2
-x+4.5Y=7

Answer 1

Explanation:

x - 2.6y = -3.2 --------------(i)

-x + 4.5Y = 7 ----------(ii) {Add the two equations. So, x will be eliminated}

1.9y = 3.8

y = 3.8/1.9

y = 2

Plug in the the value of y in equation (i)

x - 2.6*2 = -3.2

x - 5.2 = -3.2

x = -3.2 + 5.2

x = 2
