ANSWER
The painting would cost $387.45.
____________________________________________________________
EXPLANATION
2' 3" = 27"
3' 5" = 41"
Multiply the length by the width (in inches) of the painting.
27 * 41 = 1107
We now know that the area of the painting is 1107 Next, multiply the cost per square inch (0.35) by the total amount of square inches (1107).
.35 * 1107 = 387.45
A system of equations with infinitely many solutions is a system where the two equations are identical. The lines coincide. Anything that is equal to 
will work. You could try multiply the entire equation by some number, or moving terms around, or adding terms to both sides, or any combination of operations that you apply to the entire equation.
You could multiply the whole thing by 4.5 to get
. If you want, you could mix things up and write it in slope-intercept form: 
. The point is, anything that is equivalent to the original equation will give infinitely many solutions x and y. You can test this by plugging in values x and y and seeing the answers!
The attached graph shows that four different equations are really the same.
