Question

50x+200=20(x-4)+100.



B)14t-9 -3t=2t+36

C)6m+3(10-4m)=25+8m

Answer 1

a) 50x + 200 = 20(x-4) + 100
50x + 200 = 20x - 80 + 100
50x - 20x = -80 + 100 - 200
30x = -180
x = -180 / 30
x = -6

b) 14t - 9 - 3t = 2t + 36
14t - 3t - 2t = 36 + 9
9t = 45
t = 45 / 9
t = 5

c) 6m + 3(10 - 4m) = 25 + 8m
6m + 30 - 12m = 25 + 8m
6m - 12m - 8m = 25 - 30
-14m = -5
14m = 5
m = 5 / 14
