Answer:
The solution of given equations are (17 ,7).
Step-by-step explanation:
The given equations are
x = 10 +y ......(1)
x - 5 y = -18 ......(2)
substitute 'x' value in equation (2) , we get
10 +y - 5 y = -18
subtracting '10' on both sides, we get
10 - 4 y -10 = -18 -10
cancelled '10' on left hand side,we get
-4 y = -28
dividing '4' on both sides and simplification we get
y = 7 .....(3)
substitute the y= 7 in equation (1)
x = 17
the solution of given system is (17 ,7).
verification:-
put x = 17 and y= 7
x - 5 y = -18
17 - 5 (7) = -18
17 - 35 = -18
-18 = -18
