Question

solve the linear equations below:

Answer 1

4x - 3y = 17
5x + 4y = 60

Answer 2

You just need to replace like this. First:

4x-3y=17 is 4x=17+3y is \[x=\frac{ 17 + 3y }{ 4 }\] The you insert that x into the second equation:\[(5 \times \frac{ 17 + 3y }{ 4 })+4y = 60 \rightarrow y= \frac{60-(5 \times \frac{ 17 + 3y }{ 4 }) }{ 4 }\]Then you solve for y and instert that back into the first equation and solve for x

Answer 3

Thank you do much this is a very helpful way to solve linear equations :)
