3x+2=11
(you need to isolate x, so step 1 is to subtract 2 from both sides.)
3x+2-2=11-2
3x=9
(then divide both sides by 3)
3x/3=9/3
x=3

Answer:
1(20-x)
Step-by-step explanation:
let the number of correct answers be x
so wrong will be 20-x
1 mark cancelled from each question
therefore,
1(20-x) will be the answer
Y = 2(x – 2)+1
y = 2x – 4+1
y = 2x-3
insert x=0 -> y=-3, only the first graph passes through (0,-3) -> it is the first graph
