Solve for x:
2x - 4y = 8

• y = (2x - 8) / 4
  
• x = (4y + 8) / 2
• 2x = 4y - 8
• x = (-4y - 8) / 2

Solve for p:
p*t = m

• t = m/p
• p = t/m
• p = m - t
• p = m/t

Solve for g:
ag - bx + w = 2m

• g = (2m + bx - w)/a
• g = 2m + w + bx + a
• g = -bx + w / a + 2m
• a = (bx - w + 2m)/g

What is an invalid answer for the equation:
p/q=t

• p=t*q
• p=q/t
• q=p/t
• p=q*t
