Answer:
x=2
y=3
Step-by-step explanation:
The first one would be the right one!
you just take all the y one side and the numbers on one side
so 8y+4= 6+3y
now 8y-3y= 6-4
therefore 5y = 2

We need to solve how much it cost to paint a room with are 459 ft² given that a room with an area of 306 ft² costs $72. The solution is shown below:
Cost per area = $72 / 306 ft²
Cost per area = $0.2353 / ft²
Solving the cost for the similar room:
Costs = $0.2353 * 459 ft²
Costs = $108
The answer is $108.
Answer:
y=1.7x + 1.3
Step-by-step explanation:
16x + 15y =20
therefore we make the variable stand on its own
15y = 20 - 16x
Divide both sides by the variable which is 15.
it will be y= 1.3 - 1 7x
so therefore the answer is :
y= 1.7x + 1.3
