The correct answer is option 1: x = -4y+19
Step-by-step explanation:
Given equations are:
[tex]3x+2y=17\ \ \ Eqn1\\x+4y=19\ \ \ \ Eqn2[/tex]
When we have to solve a system of equations using substitution method we look for a variable in both of equations that is without any co-efficient as it is easy to isolate that variable in the equation and then using substitution method to solve it
We can see that in equation 2, x is without any co-efficient
So,
[tex]x+4y = 19[/tex]
Subtracting 4y from both sides
[tex]x+4y-4y = 19-4y\\x = 19-4y\\[/tex]
Can also be written as:
[tex]x = -4y+19[/tex]
Hence,
The correct answer is option 1: x = -4y+19
