Answer:

(23, 4)

Step-by-step explanation:

If we use substitution, we need to rewrite the 2nd equation so we can substitute it into the first.

Step 1: Rewrite 2nd equation

x = 5y + 3

Step 2: Substitution

2(5y + 3) - 5y = 26

Step 3: Distribute

10y + 6 - 5y = 26

Step 4: Combine like terms

5y + 6 = 26

Step 5: Isolate <em>y</em>

5y = 20

y = 4

Step 6: Find <em>x</em>

x - 5(4) = 3

x - 20 = 3

x = 23

And we have our final answer!

HELP JUST 1 AND 2 PLEASE HURRY WRITE THE NOUNS AND TELL WHETHER EACH IS COMMON OR PROPER
Andrews [41]

For #1 it's going to be proper because it's pretty specific, and for number two it's going to be all common because it's not citing anything specific.

What does 4/54=x/36 equal
dalvyx [7]

First reduce the fraction so your equation looks like this:

2/27=x/36

Now cross multiply to simplify

72=27x

Now change sides

27x=72

Now divide both sides by 27

X= 8/3

Now you are left with your answer:

x= 8/3

Hope this helps! :3
