To find the intercept of a variable in a equation with more than one variable, you need to equal the others variables to zero.
-> 4x -6y -5z = 60
-> X-Intercept:
To find the X intercept, equal the Y and Z values to 0.
(Y = 0; Z = 0)
4x -6(0) -5(0) = 60
4x = 60
x = 60/4
x = 15
-> Y-Intercept:
To the Y intercept it's the same thing, equal the another variable values to 0.
(X = 0; Z = 0)
4(0) -6y -5(0) = 60
-6y = 60
-y = 60/6
-y = 10 x(-1)
y = -10
-> Z-Intercept:
(X = 0; Y = 0)
4(0) -6(0) -5z = 60
-5z =60
-z = 60/5
-z = 12 x(-1)
z = -12
Answer: The intercepts for this equation (15,-10,-12).
Or: x = 15, y = -10, z = -12.

<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
From the prism:
Perimeter P = 2(w + l)
40 = 2(w + l)
w + l = 20 (1)
Also:
Base area (B) = wl
100 = wl (2)
from equation 1 and 2:
w = 10, l = 10
The dimensions of the prism has height of 7 units, width of 10 units and length of 10 units.
