Question

2x² = 5 + y

4y = -20 + 8x²

Solve the first equation for y and substitute it into the second equation. The resulting equation is

Answer 1

nah i can do it the other way around... the second one then the first one

Explanation:

2x^2 = 5 + -5 + 2x^2

Which simplifies down to 2x^2 = 2x^2

Answer 2

2x² = 5 + y --------- y=2x2−5

4y = -20 + 8x²---------- y=2x2−5

Explanation:

1: Step 1: Flip the equation.

y+5=2x2

Step 2: Add -5 to both sides.

y+5+−5=2x2+−5

y=2x2−5

2: y=2x2−5

Hope this helps.
