Answer:
The value of x = 5 and the value of y = 9
Step-by-step explanation:
It is given that,
x = 5 -----(1)
y = 2x - 1 -----(2)
Using these two equations we can calculate the value of y using substitution method.
Substituting the value of x from eq(1) to eq(2)eq(2) becomes,
y = 2*5 - 1
y = 10 - 1
y = 9
Therefore the value of y = 9 and value of x = 5
Y is 9 because 2 times 5 is 10, then you take that same 10 and subtract 1 and then you have 9
