12-3(2w+1)=7w-3(7+w)?

Question

Help me solve this please

Answer 1

12-6w-3=7w-21-3w

9-6w = -21+4w

30 = 10w

w = 3

Answer 2

w=7^16 or (0.4375)

Answer 3

12-6w-3=7w-21-3w..........12-3=9 and 7w-3w=4w

9-6w=4w-21.........add 21 to each side..........add 6w to each side

30=10w..........divide each side by 10

3=w

Answer 4

ok

12-3(2w+1)=7w-3(7+w)

first we do the multiplying thing

we'll have

12-3(2w)+(-3)(1) = 7w-(3)(7)+(-3)(w)

then we'll have

12-6w-3 = 7w-21-3w

we add the similar entities

-6w+(12-3) = (7w-3w)-21

so it'll be

-6w+9 = 4w-21

then we insolate "w"

-6w-4w = -21-9

be get

-10w = -30

be divide by -10

w = 3

Congrats

Probe

12-3(2(3)+1) = 7(3)-3(7+3)

12-3(6+1) = 21-3(10)

12-21 = 21-30

-9 = -9
