Answer:
x =
[tex] - \frac{ 1}{7} [/tex]
y =
[tex] \frac{61}{7} [/tex]
Step-by-step explanation:
Since both expressions 2x+9 and 9x+10 are equal to y, set them equal to each other forming an equation in x
2x+9 = 9x+10
Now, solve the equation:
2x-9x = 10-9
-7x = 1
x =
[tex] - \frac{1}{7} [/tex]
Then, substitute the given value of x in any of the two equations given, let's take y = 2x+9
y = 2×(-1/7)+9
y =
[tex] \frac{61}{7} [/tex]
That's it! I hope that this explanation was helpful ;)
