Answer:
21
Step-by-step explanation:

Answer:
{x,y} = {25/9,23/9}
Step-by-step explanation:
// Solve equation [2] for the variable x
[2] x = -4y + 13
// Plug this in for variable x in equation [1]
[1] 5•(-4y+13) + 2y = 19
[1] - 18y = -46
// Solve equation [1] for the variable y
[1] 18y = 46
[1] y = 23/9
// By now we know this much :
x = -4y+13
y = 23/9
// Use the y value to solve for x
841,620. 841.620. 841-620. 026,148
This is a one variable equation in algebra.
X = 2
Answer:
Rational
Step-by-step explanation:
Because it's an actual number that you can graph where irrational would be is if it would be a number that like pie or something where it just goes on and on
