Answer:
$653
Explanation:
:]
Let's use x to represent the cost of one refrigerator and y to represent the cost of one fan.
The equations become:
Equation 1: x + 2y = 1219
Equation 2: 2x + 3y = 2155
Using the same substitution method:
From Equation 1, we have:
x = 1219 - 2y
Substitute this expression for x in Equation 2:
2(1219 - 2y) + 3y = 2155
Simplify the equation:
2438 - 4y + 3y = 2155
-y = 2155 - 2438
-y = -283
===> y = 283
Now substitute the value of y back into Equation 1 to find x:
===> x + 2(283) = 1219
===> x + 566 = 1219
===> x = 1219 - 566
===> x = 653
Therefore, the cost of one refrigerator is $653.
