Remember PEMDAS.
Parentheses first, which is 3. So then that is 5 times 3 times 2 divided by 3 +11

30divide 3 +11
10+11
answer is 21
7(y+2)=3
seven times the sum of a number (y) and 2
means y+2 multiplying by 7
Answer:
1/2
Step-by-step explanation:
-2y= 8-X
y= -4+X/2
y= X/2-4
recall that: y= mx+c
in the equation y= x/2+C
m=1/2
where m is your slope
