Which equations have the same value of x as 5/6x+2/3=-9 Check all that apply

grigory [225]

Answer:

$6[\frac{5}{6}x+\frac{2}{3}]=-9*6$

$5x+4=-54$

$5x=-58$

Step-by-step explanation:

we have

$\frac{5}{6}x+\frac{2}{3}=-9$

Solve for x

Multiply by 6 both sides to remove the fractions

$6[\frac{5}{6}x+\frac{2}{3}]=-9*6$

$5x+4=-54$

Subtract 4 both sides

$5x=-54-4$

$5x=-58$

Divide by 5 both sides

$x=-58/5$

$x=-11.6$
