an appliance store sells a washer dryer combination for $1500 if the washer costs $200 more than the dryer find the cost of each
adelina 88 [10]
Make an equation

X+X+200=1500

Isolate the variable

2x=1300

X=650

Know that we know what X is, we know that X + 200 will equal the cost of the second appliance

650+850=1500
