Answer:
x=5 , y=4
Step-by-step explanation:
4x-3y=8
x-2y=-3 (Multiply the 2nd equation into 4 to make it 4x-8y = -12)
Now, the 2 equations are:
4x-3y=8
4x-8y = -12 (Subtract the 2 equations)
We get , (4x-3y)-(4x-8y)=8-(-12)
=> 5y=20
=> y=4
Therefore, substituting y in either of the equation, we get: x=5
Therefore, you answer is:
x=5 , y=4
