Find the value of 4w +1 given that -3w-7=2.
Simplify your answer as much as possible.

-11

Step-by-step explanation:

-3w - 7 = 2

-3w (- 7 + 7) = 2 + 7

-3w = 9

-3w/-3 = 9/-3

w = -3

4w + 1

4(-3) + 1

-12 + 1

-11

4w + 1 = -11

Step-by-step explanation:

Solving -3w - 7 = 2

By adding 7 to both sides of the equation  we get -3w = 9

to get to w = ... we need to divide both sides with -3, which gives us

w = -3. You can check this answer by putting it back into the original equation ( -3 * -3 - 7 does equal 2,  which means our solution for w is correct.

Now all we have to do is put our solution for w into the remaining equation:

4 * -3 + 1 = -12 + 1 = -11

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.

i think the answer is a.( -3, -1 )
