Please help! Thank you!

Answer 1

`\huge \boxed{ \boxed{ \sf \: y = x + 15}}`

Explanation:

to understand this

you need to know:

• linear equation
• linear equation word problems
• PEMDAS

tips and formulas:

• linear equation:y=mx+b

let's solve:

all we need to care about the middle condition which is

the new test score is 15 points more than the original score

given that

original score is x

New score is y

if you pay attention to the given condition

we can find it same as linear equation

therefore

according to the question

the equation is

y=x+15
