1) solve for w: 3w - 10 = 4w + 5

2) solve for t:6 - 2t >18

Problem # 1

3w-10=4w+5

(3w-10) + (10-4w) = (4w+5) + (10-4w)

(3w-10) + (-4w+10) = (4w+5) + (-4w + 10)

3w-10-4w+10 = 4w + 5 - 4w + 10

3w-4w=15

-w=15

w = - 15 (w is negative 15)

problem #2.

6-2t > 18

6-2t-6 > 18-6

-2t > 12

(-1) (-2t) > 12 (-1)

2t > - 12

next divide by 2

2t/2 > - 12/2

t > - 6 (t is greater then negative 6)
