Question 1
5v + 150 = - 100
5v = - 250
v = - 50

Question 2
25w - 2000 = - 3000
25w = - 1000
w = - 40

.5v + 15 = -10
.5v = -25
v = -25/0.5 = -50

-.25w - 20 = -30
-.25w = -10
w = -10 / -.025 = 40

1)
0.5v + 15 = -10
0.5v = -25
v = -25/0.5
v = -50

2)
-0.25w - 20 = -30
-0.25w = = -10
w = -10/-0.25
w = 10/0.25
w = 40
