I already answered this question, if you look back in your questions you should find this answered along with another one. I'll do it again just in case you don't find it.

Answer:

{y,x} = {-4,-2}

Expanation:

Solve by Substitution :

// Solve equation [1] for the variable y

[1] y = 2x

// Plug this in for variable y in equation [2]

[2] -2•(2x) - 8x = 24

[2] - 12x = 24

// Solve equation [2] for the variable x

[2] 12x = - 24

[2] x = - 2

// By now we know this much :

y = 2x

x = -2

// Use the x value to solve for y

y = 2(-2) = -4

A stage designer paid $4 per square foot for flooring to be used in a square room. If the designer spent $600 on the flooring, a

Answer:

A square has equal width and length. To find the area, you have to multiply the width by length but because they are the same length, you may some time see the formula written as L*L or $L^{2}$ .

The area of used up by the squares is 150sq feet. I found this by dividing 600 by 4. You can find an estimate by equating 150 the L*L. This gives you an approximate value of 12.
