Question

Two variable equation

LET x=0 x-2y=4 what is the value of y?


Solve for the missing variable: LET y=0: x-2y=4 what is the value of x?



​

Answer 1

Explanation:

(i) Let x = 0 and x-2y=4

Put x = 0 in x-2y=4

0-2y=4

-2y=4

y=-2

If x = 0, the value of y is -2.

(ii) Let y=0 and x-2y=4

Put y = 0 in x-2y=4

x-2(0)=4

x=4

If y = 0, the value of x is 4.
