If 3x+2=5/9, what is the value of −3x+8?<br><br>Group of answer choices
allsm [11]

Answer:

= 4

Step-by-step explanation:

first lets find the value of x in 3x+2=5/9

3x+2=5/9

3x = \frac{5}{9} -2

3x = \frac{3}{9}

3x = \frac{1}{2}

x = \frac{1}{2 * 3\\ }

x = \frac{1}{6}

\frac{1}{6} can also be written as 6^{-1}

−3x+8

-3 (\frac{1}{6}) +8

\frac{-3}{6} +8

= 4
