5x + 10 = 20

Mathematics
1 answer:
Andrei [34K]3 years ago
4 0

To solve for <em>x</em>, we must first isolate the term containing <em>x</em> which in this problem is 5x.

Since 10 is being added to 5x, we subtract 10 from both sides of the equation to isolate the 5x.

On the left, the +10 and -10 cancel out and on the right, 20 - 10 is 10 and we have 5x = 10.

Now we can finish things off by just dividing both sides of the equation by 5. On the left the 5's cancel and on the right, 10 divided by 5 is 2 so <em>x = 2</em>.

The Black line is the graph of y=c. Which of these equations could represent the blue line?
galben [10]
C. y = 0.5x.

The coefficient of x is the slope of the line. From the picture, you can see that the slope of the blue line is half the slope of the black line.
