-(1+7x)-6(-7-x)=36 -- expand brackets
-1-7x+42+6x=36 -- combine like terms
41-x=36 -- add x to both sides and subtract 36 from both sides
5=x

x=5

(6h + 8) - (3h + 2) = 15<br> PLEASE HELP I ALSO NEED TO SHOW WORK

Anestetic [448]

Answer:

$h=3$

Step-by-step explanation:

So we have the equation:

$(6h+8)-(3h+2)=15$

First, let's distribute the negative:

$(6h+8)+(-3h-2)=15$

Combine like terms:

$(6h-3h)+(8-2)=15$

Subtract or add:

$3h+6=15$

Subtract 6 from both sides:

$3h=9$

Divide both sides by 3:

$h=3$

And we're done!
