Answer:

w=7

first, take the like terms to one side of the equation:

-3w+9w=49-7

this simplifies to:

6w=42

[tex]w = \frac{42}{6} [/tex]

w=7

Answer:

w=7

-3w+7=-9w+49

do inverse operations to isolate w.

add 9w to get all the w on one side:

6w+7=49

take away 7:

6w=42

divide by 6:

w=7

hope this helps :)
