Step-by-step explanation:
Using the first equation, solve for x:
[tex]3x+8y=15\\[/tex]
Subtract 8y from both sides
[tex]3x+8y-8y=15-8y\\3x=15-8y[/tex]
Divide both sides by 3
[tex]\frac{3x}{3}=\frac{15-8y}{3} \\\\x=5-\frac{8y}{3}[/tex]
Keep that in mind...Now solve for y
[tex]3x+8y=15[/tex]
Subtract 3x from both sides
[tex]3x-3x+8y=15-3x\\8y=15-3x[/tex]
Divide both sides by 8
[tex]\frac{8y}{8}=\frac{15-3x}{8} \\\\y=\frac{15-3x}{8}[/tex]
Now, plug these into 2x+8y
[tex]2(5-\frac{8y}{3})+8(\frac{15-2x}{8})[/tex]
Simplify
[tex]10-\frac{16y}{3} +15-2x\\\\-2x-\frac{16y}{3} +25[/tex]
omg nevermind
it goes on forever
You don't solve this
Unless....
You messed up on 2x+8y and forgot the equal sign, which would make it an equation...I got played.
