There are three steps

1 rearrange the equation so "y" is on the left and everything else is on the right

2 plot the "y=" line (make it a solid line for y< or y> and a dashed line for y< or y>)

3 shade above the line for a "greater than" (y> or y>) line under that or below the line for a less than (y< or y< line under it)

7/7q+21= x /5q^2-45 then x=?

anzhelika [568]

Answer:

x = 5q - 15

Step-by-step explanation:

$\frac{7}{7q+21}=\frac{x}{5q^{2}-45}\\\\\frac{7}{7(q+3)}=\frac{x}{5 (q^{2} -9)}\\\\frac{1}{q+3}=\frac{x}{5*(q^{2}-3^{2})}\\\\\frac{1}{q+3}=\frac{x}{5(q+3)(q-3)}\\\\\frac{1}{q+3}*5*(q+3)(q-3)=x\\\\5(q-3)=x\\\\x= 5q-15$
