Eli and Samantha work at a dry cleaners ironing shirts. Eli can iron 20 shirts per hour, and Samantha can iron 35 shirts per hou
Tomtit [17]

Answer:

see the explanation

Step-by-step explanation:

Let

x ----> the number of hours Eli worked

y ----> the number of hours Samantha worked

we know that

Eli and they ironed 400 shirts between them

so

20x+35y=400 -----> equation A

Samantha worked 2 more hours than Eli

so

y=x+2 ----> equation B

solve the system by substitution

substitute equation B in equation A

20x+35(x+2)=400

solve for x

20x+35x+70=400\\55x=330\\x=6

Find the value of y

substitute the value of x in equation B

y=6+2=8

therefore

The number of hours Eli worked was 6 and the number of hours Samantha worked was 8
