Solving Equations
Hey everybody, I need some help with the following equations:
g + b =y solve for b a/b = c solve for a x/y = z solve for x x/y + k = p solve for x xyz = m solve for y c = 5p + 215 solve for p 0.4x  0.2 = 1  Please and thank you for the help.

g + g + b = y + g 0 + b = y + g b = y + g 2. a/b = c b(a/b) = bc (b/b)(a) = bc 1(a) = bc a = bc 3. Same as number 2. 4. x/y + k = p x/y + k  k = p  k x/y + 0 = p  k x/y = p  k y(x/y) = y(p  k) (y/y)(x) = y(p  k) 1(x) = y(p  k) x = y(p  k) 5. xyz = m yxz = m (yxz)/(xz) = m/(xz) y = m/(xz) 6. c = 5p + 215 c  215 = 5p + 215  215 c  215 = 5p + 0 c  215 = 5p (c  215)/5 = 5p/5 (c  215)/5 = p 7. 0.4x  0.2 = 1 0.4x  0.2 + 0.2 = 1 + 0.2 0.4x + 0 = 1.02 0.4x = 1.02 0.4x/0.4 = 1.02/4 x = 0.255
