Answer:
a: 15
b: 36
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.
