Answer:
c=40
Step-by-step explanation:
a + c=65 equation 1
7a+4c=335 equation 2
c=65-a isolate c from equation 1
7a+4(65-a)=335
7a+260-4a=335
3a=75
a=25
solve for c
a+c=65
25+c=65
c=40
check answer:
7a+4c=335
7(25)+4(40)=335
175+160=335
335=335

Describe, in great detail, how you would put a line into slope-intercept form (y = mx + b) if it wasn't already, so that it would be ready to graph.
Use 2y - 4x = 104 as your example.
Answers
Answer:
y=2x+52
Step-by-step explanation:
you would put y to one side so subtract 4x from the side with y and move it to 104
2y=104+4x
Now divide by 2 so you have y alone
y=52+2x
answer y=2x+52
