If you need an equation it is -3.4x=21.5
You simply divide both sides by -3.4 to get x=-6.32
if that's not right then just get on a calculator and calculate by doing what I said to divide
Firstly we are looking for two variables x,y so that we need two formulas .
the second formula is missing
3y+14=44
Answer: First step is to subtract 14 from each side
3y = 30 (divide each side by 3)
y = 30/3, y = 10
Answer:
The total cost will be $40 plus $1.50 per square foot of carpet or $40+$1.50x
