Answer:
x=20
Step-by-step explanation:
we know the straight angle theorum...
3x+80+2x=180
5x=100
x=20
It can lie between any number lower than it and any number high than it.
For example, 419 and 421
Answer:
X = 7 Y = -19
Step-by-step explanation:
If you want to solve this equation by substitution then you have to put the second equation in, so it will look something like this
5x + 1(2-3x)=16
Apply distributive property to solve.
Once you find x, plug it in to find y
To double check your work, you can plug the coordinated values back in
-19 = 2 - 3(7)
-19 = 2-21
This is true, so our solution is correct.
