2940+11760=x\times 42
Multiply 210 and 14 to get 2940. Multiply 420 and 28 to get 11760.
14700=x\times 42
Add 2940 and 11760 to get 14700.
x\times 42=14700
Swap sides so that all variable terms are on the left hand side.
x=\frac{14700}{42}
Divide both sides by 42.
x=350
Divide 14700 by 42 to get 350.
