Step-by-step explanation:
Hey, you have to put the number in replacement of the letter you know? Ex #1.) 3x + y. x=3 y=5
So you would rewrite the equation as

Answer:
Step-by-step explanation:
x² + 25 = 36 ⇒ <em>x</em> = √11 ≈ <em>3.3 </em>
5y = 11 ⇒ <em>y </em>= 11 ÷ 5 <em>= 2.2</em>
z = y + 5 ⇒ <em>z = 7.2</em>
The answer is 1 and 1/24. You add the numerators and the denominators across then simplify.
