Question

solve the following simultaneous equation x - 2y=-1,2x-y=7

Answer 1

That's the solution..

Answer 2

Answer:

x = 5 and y = 3

Step-by-step explanation:

Given equations are,

x - 2y=-1.........(1)

2x-y=7......(2)

we need to solve these equations that means we need to find the value of x and y.

multiply equation (1) by 2, and subtract it from eqution (1), we will get

(2x-y) - 2(x - 2y) = 7 - (-2)

=> 3y = 9

=> y = 3

Now, put the value of y in equation (1), we will get

x = -1 +2(3)

=> x = 5

Hence, the solution of given equations are x = 5 and y = 3.
