Question

Solve the following using the substitution method and find the value of x and y:
-5x - 4y = 32
2y = -6

  1. 1, 4
  2. 4, 5
  3. -4, -3
  4. -5, -8

hintHint:

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.
