Answer:

x=-3

y=6

Step-by-step explanation:

Elimination method:

2x+7y=36

6x-7y=-60

Add these equation to eliminate y:

8x=-24

Then solve 8x=-24 for x:

8x=-24

\frac{8x}{8} =\frac{-24}{8}

x=-3

Add the value of x to solve y:

2x+7y=36

Substitute -3 for x in 2x+7y=36

(2)(-3)+7y=36

7y-6=36

7y=36+6

7y=42

y=42/7\\

y=6

{ x=-3 and y=6 }

<em>hope this helps....</em>

To paint interior​ walls, a person charges 50¢ per square foot plus the cost of the paint. For a recent​ job, the paint cost ​$1
KatRina [158]

Answer:

750 ft²

Step-by-step explanation:

.Given :

Charge per ft² = 50¢ = $0.5

Total cost = ((charge per ft² * number of ft²) + cost of paint)

Given that :

Paint cost = $100

Total cost = $475

Number of ft² = x

Plugging values into the equation :

475 = (( 0.5 * x) + 100)

475 = 0.5x + 100

475 - 100 = 0.5x

375 = 0.5x

x = 375 / 0.5

x = 750 ft²
