So we multiply both sides by 7 to make 2/7 a whole number. You get 2(4q+7/2)-21q=63. Then take 4q+7/2 out of parentheses and you get 8q+7-21q=63. Subtract 7 on both sides and add the q’s together, -13q=56. Divide both sides by -13 and you get around 4.3

Answer:

x=<u>+</u> $\frac{\sqrt{4y-7}-1 }{2}$

Step-by-step explanation:

Quadratic function =( -b<u>+</u> $\sqrt{b^2+4ac}$ )/2a

x^2+x+2-y=0

x=-1<u>+</u> $\sqrt{1^2-4(2-y)}$ /2

x=-1<u>+</u> $\sqrt{4y-7}$ /2

x=<u>+</u> $\frac{\sqrt{4y-7}-1 }{2}$

Pretty sure this is right. Would appreciate a brainliest
