Solve by showing all work on paper. After you are done, take a clear picture and submit here. 1. 3x + 1 = 10

2. -4w - 4 = 8

3. y + 12 = 15

4. 8 = m - 3

Step-by-step explanation:

1.

we have to added  up -1 at the two members of the equation

3x+1-1 = 10-1

3x = 9

we have to divide the two members of the equation by 3  

3x/3 = 9/3

x = 3

2

we have to added up 4 at the two members of the equation

-4w-4+4 = 8+4

-4w = 12

we have to divide the two members of the equation by -4

-4w/-4 = 12/-4

w = -3

3

we have to added up -12 at the two members of the equation

y +12 -12 = 15-12

y = 15-12

y = 3

4

we have to added up 3 at the two members of the equation

8+3 = m-3+3

m = 8 + 3

m = 11

i understand 100% 10/10 hit or miss?
