Answer:
x = 1.153846153846154
y = -1.923076923076923
Step-by-step explanation:
Multiply 7x - y = 12 by -4 and then add it to 2x - 4y = 10
2x - 4y = 10
+(-4( 7x - y = 12))
-26x = -30
x = 1.153846153846154
Then plug in x to get y.
2(1.153846153846154) - 4y = 10
2.307692307692308 - 4y = 10
-2.307692307692308 -2.307692307692308
-4y = 7.692307692307692
y = -1.923076923076923
Answer:
The number of tiles are covered by the painting are 12.
Step-by-step explanation:
Consider the provided information.
The painting is covering up some of the tiles on the wall as shown below:
Here it is given that there are 28 squares tiles on the wall.

28 = Number of tiles covered by the painting - 16
Number of tiles covered by the painting = 28 - 16
Number of tiles covered by the painting = 12
Hence, the number of tiles are covered by the painting are 12.
