Question

Given the system of equations {y=−16x^2+20x+6 y=7x+3} solve by substitution.

Set the expressions on the right side of each equation equal to each other and rearrange so that it is in standard form.

Which is the correct standard form equation?

Answer 1

y=7x+3
{(7x+3)}=16x^(2)+20x+6

this is when you do by substitution.
