Answer:
There is no solution to this system.
Step-by-step explanation:
The left side of the first equation is 3 times the left side of the second one.
If we multiply the whole of the second equation by 3 we get:
3x - 6y = -16.
As the first equation is 3x - 6y = -12 we see that there is no solution to this system. 3x - 6y can't be equal to -12 and -16.
Square 33 is the first square in Row 5, the first square of the second half of the chessboard. How many pennies are on square 33?
Answer : 2^32
Answer:
2x - 7 = 8
2x = 8 + 7
2x = 15 (divide both sides by 2 to get x)
2x/2 = 15/2
x = 7.5
Step-by-step explanation:
Y = 3(x + 2) + 4
Y = 3x + 6 + 4
Y = 3x + 10
