Answer:
x = 19/5
Step-by-step explanation:
5x-4y = 17
Let y = 1/2
5x-4(1/2) = 17
5x -2 = 17
Add 2 to each side
5x-2+2 =17+2
5x=19
Divide by 5
5x/5 = 19/5
x = 19/5
A coefficient is a numerical or constant quantity placed before and multiplying the variable in an algebraic expression (e.g. 4 in 4x).
The 2 and + are out since they don't have variables(and the + is just a +).
So 4 and x are left. x is a variable, not a coefficient, so the last(and correct) answer is 4.
