Question

What is the question?

Answer 1

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 y

5y = 20

y = 4

Step 6: Find x

x - 5(4) = 3

x - 20 = 3

x = 23

And we have our final answer!

Answer 2

Answer:

(23,4)

Step-by-step explanation:

x-5y=3

 +5y=+5y

    x=3+5y

-- Plug that into X for the other Equation

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

Solve for y

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

Distribute the 2

6+10y-5y=26

Simplify

6+5y=26

-6     =-6

5y=20

(divide by 5)

y=4

plug 4 in the either equation and solve for x

x-5(4)=3

x-20=3

+20=*20

X=23
