Answer:

a: 15

b: 36

Step-by-step explanation:

question A

The question provides you with 5x+3=17.

So first, subtract 3 from both sides to get 5x=14

Now since we know 5x=14, we can plug this into the expression 5x + 1.

14 + 1 is 15.

question B

the question gives you the equation 5 - 3y = 6. Next it wants you to find

(5 - 3y)². If we know 5 - 3y = 6, we can turn this equation, (5 - 3y)²

into this: 6² (because we can substitute the expression with 6)

6² is 36.
