In a mathematics test, shane scored 17 marks more than tom while sophie 's score is twice of tom 's score. if their total is 161 , what is shane ' s score?
( linear equations)

Let Tom = x

Then Shane is x +17 ( 17 more than Tom)

Sophie  = 2x ( twice Tom's score)

Now you have:

X  +(x+17) + 2x = 161

Simplify:

4x +17 = 161

Subtract 17 from both sides:

4x = 144

Divide both sides by 4:

x = 144 / 4

x = 36

Shane = x +17 = 36 +17 = 53

The correct answer is:  h(x) = 5 or y = 5

Step-by-step explanation:

h(-2) = 3(-2) + 1

h(x) = -5

y = 5

This is because h(x) is another way of writing Y.
