Question

how would i solve this system of equations algebraically? x^2+y=4 and x+y=2?

Answer 1

take the difference of the equations,
note that it has no y term,
solve for x and then substitute
back in one of the original equations to solve for y

Answer 2

stupid of me, got my math final later today, math overload..... ty

Answer 3

get the value of y in terms of x in the equation x+y=2 and substitute it into the second equation x^2+y=4,,you will be able to get x. Substitute in that value of x in any of the two equation and you'll get y

Answer 4

\[x+y=2\]
\[y=2-x\]
plug in this in first equation and solve for x :D
