Order of Operation 10) An electrician charges $45 per hour and spends $20 a day on gasoline. If he worked for seven hours, write an algebraic expression to represent his earnings for the day.

45(x)-20

x=hours

7 hours

x=7

45(7)-20 =295

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10
