The linear equation two variables can be solved by various methods one of the methods to solve the linear equations is the substitution method. The solution of the given equation is x=2 and y=10.
The given equations are :
10x+3y=50 .... (1)
-5x-y=-20 ....(2)
Multiply equation (2) by 3 and then add the equation (1) to eliminate the variable y.
10x+3y+3(-5x-y)=50+3*-20
-5x=-10
x=2
Now putting the value of x in equation (1), and solve it further.
10*2+3y=50
3y=30
y=10
Hence, the value of x is 2 and the value of y is 10.
