The variable represents the number of times Chris washes the car.
its the first option.
tiles of X and tiles of 1 are different
3 tiles of "X" = 3X
3 tiles of " 1 " = 3
option 3 does not mean 3X, it just means 3X + 3
The answer is: Substitution property of equality.
The explanation is shown below:
1. To solve this problem you must apply the proccedure shown below:
2. When you clear the variable x from the first equation, and subtitute it into the second equation, you obtain:
<span>3x−2y=10
x=(10+2y)/3
4x−3y=14
</span>4[(10+2y)/]−3y=14
<span> y=-2
3. When you subsitute y=-2 into the first equation and clear the x, you have:
x=2
