Question

Getting trained and licensed involved a one time cost of $474. Gas and insurance costing him $2 per kilometer. Jayden will get paid $350 plus $4 per kilometer that he drives. Solve using substitution

Answer 1

y=474+2x

y=350+4x

Answer: x=62 y=598

Explanation:

Place the two equations equal to each other.

350+4x=474+2x

Then Subtract 350 from 474 which gets you to 124.

4x=124+2x

Then subtract 2x from both sides.

Which make the equation look like this: 2x=124

Now divide 124 by 2.

so x=62.

Then you will need to plug in x in one of the equations to know what y is.

I plugged it into this one: y=474+2(62)

Now solve.

It should get you to the answer of 598.

So, overall x=62 while y=598.
