Question
Solve the following using the substitution method and find the value of x and y:
4y = 8
x – 5y = -13
- 1, -3
- -3, 2
- 1, 3
- -1, -3
Hint:
The linear equation in two variable is an equation with two variable and degree one.
The correct answer is: -3, 2
We have given two equations
4y = 8………………………….. 1
x – 5y = -13………………………. 2
From 1
4y = 8
y = 2
Substituting y in 2nd equation,
x – 5(2) = -13
x – 10 = -13
x = -3
In the substitution method, we first write one variable in the form of another variable.
