Question
Solve the following using the substitution method and find the value of x and y:
-5x - 4y = 32
2y = -6
- 1, 4
- 4, 5
- -4, -3
- -5, -8
Hint:
The linear equation in two variable is an equation with two variable and degree one.
The correct answer is: -4, -3
Step 1 of 1:
We have given two equation
-5x – 4y = 32………………………………… 1
2y = -6 …………………………………. 2
From 2
2y = -6
y = -3
Substituting y in 1st equation,
-5x – 4(-3) =32
-5x + 12 = 32
-5x = 32 – 12
-5x = 20
x = -4
In the substitution method, we first write one variable in the form of another variable.
