Question
Solution 1
The system of equations given is:
- 4x + y = -4
- 7x + 3y = 3
Step 1: Solve the first equation for y.
y = -4 - 4x
Step 2: Substitute y in the second equation with the expression we found in step 1.
7x + 3(-4 - 4x) = 3 7x - 12 - 12x = 3 -5x - 12 = 3 -5x = 15 x = -3
Step 3: Substitute x = -3 i Knowee AI is a powerful AI-powered study tool designed to help you to solve study problem.
