Question

2x-y=-9, 3y=7+4x simultaneous linear equations please answer my question​

Answer 1

Answer:

x= (-10) and y= -(11)

Step-by-step explanation:

2x - y = (-9) .....(i)

4x - 3y = (-7) .....(ii)

Now, Add the equation (i)*(-2) and (ii)

(-4x) + 2y = 18

4x - 3y = (-7)

=> -y = 11

therefore, y= (-11)

Substitute the value of y in eq (i)

2x - (-11) = (-9)

2x = (-20)

therefore, x= (-10)

So, value of x= (-10) and y= -(11)
