Answer:
Step-by-step explanation:
Isolate the term of x and y from one side of the equation.
<h3>x+2y=11 and 4x-y=8</h3>⇒ x+2y=11
⇒ x=11-2y
Substitute.
4(11-2y)-y=8
<u>Solve.</u>
<u>Distributive property:</u>
⇒ A(B+C)=AB+AC
4(11-2y)
4*11=44
4*2=8
<u>Rewrite the problem down.</u>
44-9y=8
<u>Subtract by 44 from both sides.</u>
44-9y-44=8-44
Solve.
-9y=-36
<u>Divide by -9 from both sides.</u>
-9y/-9=-36/-9
<u>Solve.</u>
-36/-9=4
<u>y=4</u>
<u>Substitute of y=4.</u>
⇒ x=11-2*4
<u>Use order of operations.</u>
<u>PEMDAS stands for:</u>
- Parentheses
- Exponents
- Multiply
- Divide
- Add
- Subtract
11-2*4
<u>Multiply.</u>
2*4=8
<u>Rewrite the problem down.</u>
11-8
<u>Subtract.</u>
11-8=3
<u>x=3</u>
- <u>Therefore, the correct answer is x=3 and y=4.</u>
