What is the solution to the equation -3(h+5)+2=4(h+6)-g

dexar [7]

Answer:

$h=-4\frac{2}{7}$

Step-by-step explanation:

The given equation is

-3(h+5)+2=4(h+6)-9

We expand to obtain;

-3h-15+2=4h+24-9

Group similar terms;

-3h-4h=24-9+15

Combine the similar terms;

-7h=30

Divide both sides by -7

$h=-\frac{30}{7}$

$h=-4\frac{2}{7}$
