Answer:
Step-by-step explanation:
-x + 5y - 7 = 0
-x + 5y = 7 --------------------(I)
4y - 10 = 5x
-10 = 5x - 4y
5x - 4y = -10 -----------------------(II)
-x + 5y = 7 --------------------(I)
5x - 4y = -10 -----------------------(II)
Multiply equation (I) by 5.
(I)*5 -5x + 25y = 35
(II) <u>5x - 4y = -10</u> {Now add and x will be eliminates}
21y = 25
y = 25/21
Substitute y value in Equation (I)
-x + 5*25/21 = 7
-x + 125/21 = 7
-x = 7 - (125/21)
-x = (147/21) - (125/21)
-x = (147-125)/21
-x = 22/21
x = -22/21
