Question

Solve the system algebraically.
4x - 5y = 3
x = 3 - 1/2y
What is the value of x?
9/7
24/14
33/14

Answer 1

huh?

Answer 2

\[4x - 5y = 3\qquad \qquad x = 3 - 1/2y\]
\[4(3 - 1/2y) - 5y = 3\]\[12-4/2y-5y=3\]\[9-7y=0\]\[9=7y\]\[\frac97=y\]
\[x = 3 - 1/2\left(\frac97\right)\]\[x=3-9/7\]\[=(21-9)/7\]\[x=12/7\]
