Answer:

Step-by-step 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
