Question

Elimination:
y=6x^2
7x+y=3

Answer 1

Im certain this one isnt as simple. At least I hope so...

Answer 2

Rearrange the second equation
\(\color{#000000}{ \displaystyle 7x+y=3 }\)
\(\color{#000000}{ \displaystyle y=-7x+3 }\)

substitute this into the first equation
\(\color{#000000}{ \displaystyle y=6x^2 }\)
\(\color{#000000}{ \displaystyle -7x+3=6x^2 }\)
\(\color{#000000}{ \displaystyle 0=6x^2+7x-3 }\)

Solve this quadratic equation for x.

Answer 3

Then, after you solve for x, you can solve for y.

Answer 4

oh, didnt realize that I could substitue the 6x2 for y
