Answer:
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
