Answer:
x=-2, y=-10
Step-by-step explanation:
Since both equations are equal to y, we can set them equal to each other and solve
x-8=5x
Subtract x from both sides
-8=4x
Divide both sides by 4
x=-2
Next, we need to find a y
Substitute -2 in for x in one of the equations and solve
y=5x
y=5*-2
y=-10
x=-2, y=-10

Answer:
6 meters
Step-by-step explanation:
Every 7 floors, it goes up by 22.4 meter intervals.
Let's count down,
the 7th floor would be 50.8 - 22.4, which is 28.4.
the 0th floor would be 28.4 - 22.4, which is 6.
<span>1/3(21-3a)=6-a
I simplified the equation to the form, which is simple to understand
<span>1/3(21-3a)=6-a
Simplifying:
<span> + 0.333333333333*(21-3a)=6-a
Reorder the terms in parentheses
<span>+(+7-1a)=6-a
Remove unnecessary parentheses
<span>+7-1a=+6-a
We move all terms containing a to the left and all other terms to the right.
<span>-1a+1a=+6-7
We simplify left and right side of the equation.
<span>a=-1
<span>0=-1
The left and right sides are not equal, therefore there is no solution. This equation is invalid
