Question

solve the system y=2-x and y=4x+7

Answer 1

\(\bf {\color{red}{ y}}=2-x\\
y=4x+7
\\ \quad \\
y=4x+7\implies y=4({\color{red}{ 2-x}})+7\)

solve for "y"
then substitute that value in either equation and solve for "x"

Answer 2

hmmm lemme redo that =)

Answer 3

\(\bf {\color{red}{ y}}=2-x\\
y=4x+7
\\ \quad \\
y=4x+7\implies ({\color{red}{ 2-x}})=4x+7\)

solve for "x" rather, and then substitute that on either equation and solve for "y"

Answer 4

ok

Answer 5

so it will be (-1,3) or (1,3)

Answer 6

what did you get for "x"?

Answer 7

4x^2 I thank I gat confused with math

Answer 8

hmmm tis just a linear equation -> \(\bf ({\color{red}{ 2-x}})=4x+7\implies 2-x=4x+7\)

Answer 9

thank you that helped a lot
