Hey there!
4 + 5x + 66 = x + 10
70 + 5x = x + 10
5x + 70 = x + 10
SUBTRACT x to BOTH SIDES
5x + 70 - x = x + 10 - x
5x + 70 - 1x = 1x + 10 - 1x
SIMPLIFY IT!
4x + 70 = 10
SUBTRACT 70 to BOTH SIDES
4x + 70 - 70 = 10 - 70
SIMPLIFY IT!
4x = -60
DIVIDE 4 to BOTH SIDES
4x/4 = -60/4
SIMPLIFY IT!
x = -60/4
x = -15
Therefore, your answer is: x = -15
Good luck on your assignment & enjoy your day!

Answer:
Step-by-step explanation:
I think the question below is the one you wanted to ask:
<em>A pool has some initial amount of water in it. Then it starts being filled so the water level rises at a rate of 6 centimeters per minute. After 20 minutes, the water level is 220 centimeters
</em>
<em>Graph the pool's water level (in centimeters) as a function of time (in minutes).</em>
Here is my answer:
To draw the linear line, we need to identify the equation that modles this situation. As we know the water level rises at a rate of 6 cm per minute which mean the slope m = 6
The standard form is: y = mx + b <=> y = 6x + b
After 20min the water level is 220 cm
<=> 220 = 6(20) +b
<=> b = 100
So your equation is : y = 6x + 100 and the initial amount of water in it is 100
