1) make q the subject of the formula 4(q+p)=5+7q

2) Make x the subject of the formula y=2a-bx^2

Answer:

1) [tex]q = \frac{4p}{3} -\frac{5}{3}[/tex]

2) [tex]x = \frac{\sqrt{b -y + 2a} }{b}[/tex]

Step-by-step explanation:

1) 4(q + p) = 5 + 7q

  Multiply 4(q + p):

  4q + 4p = 5 + 7q

  4p - 5 = 7q - 4q

  4p - 5 = 3q

  [tex]\frac{4p}{3} - \frac{5}{3} = \frac{3q}{3}[/tex]

   [tex]\frac{4p}{3} - \frac{5}{3} = q[/tex]  or  [tex]q = \frac{4p}{3} - \frac{5}{3}[/tex]
