Answer:
x = -1
y = -9
Step-by-step explanation:
<u>A</u><u>d</u><u>d</u><u> </u><u>each linear equation:</u>
Sum: 5x = -5
<u>Divide each side by </u><u>5</u><u>:</u>
Quotient: x = -1.
<u>Substitute x = </u><u>-</u><u>1</u><u> into the </u><u>first</u><u> equation:</u>
4(-1) - y = 5
<u>Solve</u><u>:</u>
-4 - y = 5
<u>Add 4 to both sides of the equation:</u>
-y = 9
y = -9.
<u>Check with the second equation:</u>
-1 + -9 = -10.
Correct.
A line parallel to y = 2/3x - 7 will be y = 2/3x - 1
The slope will be the same and the y intercept can be anything. I could better find the exact line if the points of the line were given.
Hope this helps :)<span />
Answer:
y = 6.
Step-by-step explanation:
z = kx/y
9 = k*24/8
24k = 72
k = 3.
So z = 3x/y
When x = 10 and z = 5
5 = 3*10/y
5y = 30
y = 6.
