3x-12 and x-4 Identify weather the expression is equivalent. Writhe YES or NO and JUSTIFY your answer with math or words

x=4 so both the answer is 0

Step-by-step explanation:

3x-12=x-4

3x-x=-4+12

2x=8

2x÷2=8÷2

x=4

so

3x-12=4-x

3×4-12=4-4

12-12=4-4

0=0

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
