Question

BRIEFLY EXPLAIN HOW YOU FOUND YOUR ANSWERS FOR #4
4. 2y = – 4x + 12
y = - 2x + 4

Answer 1

No solution

Explanation:

We want to solve the system of equations:

`2y = 4x + 12`

`y = 2x + 4`

To do this, substitute the value of y in the second equation into the first equation:

➡️ 2(-2x + 4) = -4 + 12

-4x + 8 = -4x + 12

Collect like terms:

`- 4x + 4x = 12 - 8`

`0 = 4`

As we can see, we have that 0 is equal to 4.

This shows that the system of equations has no solution.
