Answer:
5
Step-by-step explanation:
The gradient of a line is the measure of its steepness or slope and is calculated as the ratio of the vertical change to the horizontal change between any two points on the line.
To find the gradient of the given equation y + x = 6x + 13, rearrange the equation into slope-intercept form (y = mx + b). The coefficient of x is the slope of the line.
[tex]\begin{aligned}y + x&= 6x + 13\\\\y + x-x&= 6x + 13-x\\\\y&=5x+13\end{aligned}[/tex]
Therefore, the gradient of y + x = 6x + 13 is:
[tex]\huge\boxed{\boxed{\textsf{Gradient}= 5}}[/tex]
