Answer:
The values of x and y to the given equations are x=5 and y=7
Step-by-step explanation:
Given equations are
To solve the given equations by elimination method :
Multiply the equation (1) into 2 we get
Multiply the equation (2) into 5 we get
Now subtracting the equations (3) and (4) we get
_________________
Therefore x=5
Now substitute the value of x=5 in equation (1) we get
4(5)-5y=-15
20-5y=-15
-5y=-15-20
-5y=-35
Therefore y=7
The values are x=5 and y=7
