Lindsey drew a scale drawing of the elementary school. the scale she used was 3 millimeters : 8 meters. if the actual length of the school yard is 144 meters, how long is the school yard in the drawing?due in 5 mins!

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

2

x=5

step-by-step explanation:
