Y=(-3) include parentheses 
Explanation: 
y=mx+b is the slope intercept form of a line where b and y is the intercept so, 
x-y=x+3: y= -3

Step-by-step explanation:
3x - y = 74
4y = x
Replace x in the first expression by 4y
3x - y = 74 ➡ 3(4y) - y = 74
12y - y = 74
11y = 74
y = 74/11 we can use this to find x
4y = x
4 × 74/11 = x
296/11 = x
