X= -6
Y= 3
Solve for y in the equation x+y= -3
Substitute that answer into the equation -3x+2y=24
Another way to word this ( if it helps)
The product of 15 and k is 45
So 15 times k equals 45
15k=45
This would be the equation- if we need to solve it
Divide both sides of the equation by 15 to isolate k
k=3
To solve this problem, we need to pick numbers from the table then this number will be substituted into the equation. But first, we equate the numbers such as below:
4x - 2y = 8
Transpose -2y to the right side such as:
4x = 8 + 2y
4x - 8 = 2y
(4x -8)/2 = y
2x - 4 =y
From the table, let us choose x = 0
y = 2x -4
y = 2(0) -4
y = -4
From the table, let choose another value of x such as x=1
y = 2(1) -4
y = 2 - 4
y = -2
This will prove that the values in the table are correct.
9/15 as a percent is 60%, so D.
4 1/5 as a percent is 420%, so B.
