Solve the equation 3x-4y=16 for x
3x-4y=16
add 4y to both sides
3x=4y+16
divide both sides by 3
x=(4y+16)/3
Hi there!
One little tip of advice I would like to give you is that when solving equations with 2 variables, and you're looking for only one, the second will always end up in your answer. So, since we're solving for x, the y will end up in our equation. :D
Let's begin!
\(3x - 4y = 16\)
Step 1) Add 4y to both sides.
\(3x - 4y + 4y = 16 + 4y 3x = 4y + 16\)
Step 2) Divide both sides by 3.
\(\frac{3x}{3} = \frac{4y + 16}{3}\)
\(x = \frac{4}{3} y + \frac{16}{3}\)
Final answer -
\(x = \frac{4}{3} y + \frac{16}{3}\)
