Question

Express ‘x’ in terms of ‘y’ for the equation 4x – y = 12. Also find its x-intercept

Answer 1

Answer:

$x=\frac{1}{4}(12+y)$, and the x-intercept is at (3,0)

Step-by-step explanation:

$4x-y=12\\4x=12+y\\x=\frac{1}{4}(12+y)$

The x-intercept is when the y-coordinate is 0, so

$x=\frac{1}{4}(12+0)\\x=\frac{1}{4}\times{12}\\x=3$

Since x=3 and y=0, the x-intercept is at (3,0).

Answer 2

Answer:

x=4,y=4

Step-by-step explanation:

(4×4)-(4)

16-4=12
