Group 5c-2c and 7d-3d and it comes to 3c+4d
If you meant you want to solve for c on: 5c-3 = 2c+6 you have to simplify the formula. Step 1: Subtract 2c from both sides: 3c-3 = 6 Step 2: Add 3 to both sides 3c = 9 Step 3: Divide both sides by 3 c = 3
It is a single equation of direct proportionality. It cannot be solved since that would require two linear equations.
2c = 1pt 5c = 2pt 1c
15 ac + 20 bc + 6 ad + 8 bd =3a (5c + 2d) + 4b (5c + 2d) =(3a + 4b) (5c + 2d)
