Answer: (2, 19)
Step-by-step explanation:
There are three general ways to solve a system of equations:
-<u> Substitution</u>
- Elimination
- Augmented Matric
Since both given equations all have y isolated, <u>substituting</u> the value of y will be the most appropriate way here.
--------------------------------------------------------------------------------------------------------
<u>Given</u>
y=7x+5
y=x+17
<u>Substitute y into the equations</u>
7x+5=x+17
<u>Subtract 17 on both sides</u>
7x+5-17=x+17-17
7x-12=x
<u>Subtract 7x on both sides</u>
7x-12-7x=x-7x
-12=-6x
<u>Divide -6 on both sides</u>
-12/-6=-6x/-6
x=2
<u>Substitute value into one of the equations</u>
y=x+17
y=2+17
y=19
