What is the answer to y equals x plus 2x plus 5?

Answer 1

y = x + 2x + 5 can be simplified by combining the x values. This results in y = 3x + 5. This equation can't be simplified any further or solved for either variable.

Actually the equation can be solved even further by finding the (X,Y) values. y = 3x + 5 is in Slope intercept form (y = mx + b). One can find the value of each by substituting the opposite variable with 0.

Let's solve for X.

0 = 3x + 5

-3x = 5

x = -1 2/3.

Now let's solve for Y.

y = 3(0) + 5

y = 0 + 5

y = 5

So (-1 2/3, 5) are the coordinates for your slope.
