Basically they want you to move the variables around so that it matches the standard form which is Ax+By=C.A,B,and C are just coefficients/constants.
so the original equation is
y=x-4
Minus x from both sides to move x to the left hand side.
-x+y=-4
so thats the final answer
Just subtract 6 from 18 and the answer is twelve 12.
Answer:
Step-by-step explanation:



Therefore, 6:4 and 16:8 are not equivalent ratios.
Step-by-step explanation:
Divide two on both sides to get rid of it and the make the equation in the form y = mx + c

y = 3/2x + 5
since both lines are parallel they must have the same gradient which is 3/2
y = 3/2x + c
All you have to do now is to replace x and y with (2, -5) to find c
x = 2
y = -5
-5 = 3/2 × 2 + c
-5 = 3 + c
c = -5-3
c = -8
