-63
Step-by-step explanation:
-63 plus 52 is-11. have a good day
Answer:
The solution would be (10, -3)
Step-by-step explanation:
In order to solve using elimination, multiply the top equation by -3 and then add the equations together.
-9x - 12y = -54
9x - 5y = 3
---------------
17y = -51
y = -3
Now that we have a value for y, we can put it into either equation and solve for x.
3x + 4y = 18
3x + 4(-3) = 18
3x - 12 = 18
3x = 30
x = 10
Answer:
x = 9/2 y = 0
Step-by-step explanation:
2/3x + 5y = 3 5y = -2/3x + 3 y = -2/15x + 3/5
4/3x - 2(-2/15x + 3/5) = 6
4/3x + 4/15x - 6/5 = 6
8/5x - 6/5 = 6
8/5x = 36/5
x = 9/2
2/3(9/2) + 5y = 3
3 + 5y = 3
5y = 0
y = 0
5x + 10y = 18
x = y -6, we substitute this into first equation.
5x + 10y = 18
5*(y - 6) + 10y = 18
5y - 30 + 10y = 18
So it the last option from the top.
