How do I solve the following:
A=3C+4C for C

5/9X - 13 = 27

Thanks

A=3C+4C
A = 7C
A/7 = C

C = 1/7 A

5/9X - 13 = 27

5/9x = 27 +13 when 13 moves sides it changes its sign.

5/9x = 40

x = 40* 9/5 when 5/9 changes side it reverses itself.

x = 40*9/5
x = 8*9
x = 72

Add the two C multipliers then divide both sides by the sum.

Add 13 to both sides then divide both sides by the fraction. Remember the inversion factor. The 9 is a divisor which becomes a multiplier on the other side. The five is a multiplier which becomes a divisor on the other side.

E=mgh+1-/2mv(squared) for h

E=mgh+1/2mv(squared) for h
