Answer: (60/13, 6/13)
Concept:
There are three general ways to solve systems of equations:
- Elimination
- Substitution
- Graphing
Here, we are going to use <u>elimination </u>since all the variables are in the corresponding position.
Solve:
<u>Given</u>
<u>Multiply the first equation in order to eliminate [x]</u>
<u>Subtract the second equation from the first equation to eliminate [x]</u>
<u>Divide 13 on both sides</u>
<u>Substitute [y] value in order to get [x] value</u>
4x - y = 18
4x - 6/13 = 18
4x = 18 + 6/13
4x = 240/13
Hope this helps!! :)
Please let me know if you have any questions
6.5(2r - s) + 3.7r - 1.25s.....first we distribute the 6.5 thru the parenthesis
13r - 6.5s + 3.7r - 1.25s....now we combine like terms
(13r + 3.7r) = 16.7r
(-6.5s - 1.25s) = -7.75
leaving us with : 16.7r - 7.75s <==
