Question
Solve the following using the substitution method and find the value of x and y:
-5x + 3y = -22
-5x + y = -24
- 5, 1
- 5, 2
- 5, 3
- 5, 9
Hint:
The linear equation in two variable is an equation with two variable and degree one.
The correct answer is: 5, 1
Step 1 of 1:
We have given two equations
-5x + 3y = -22....(i)
-5x + y = -24......(ii)
Rewrite first equation and then substitute
3y = 5x – 22
y= 
Now substitute the value of y in 2nd equation.
= -24
= -24
-10x – 22 = -72
-10x = -50
x = 5
Now put the value of x in 2nd equation
-5(5) + y = -24
y = -24 + 25
=1
In the substitution method, we first write one variable in the form of another variable.
