X + 8 = 0.5
Take away 8 from both sides:
x = 0.5 - 8
x = -7.5
Answer: x = -7.5

1379= 1380
38=40
1380 x 40 = 55,200

42/3=14 (price of one shirt) 100-20=80 (robert buys 5 shirt each costing 80% of the original price) 14/100x80=11.20 (price of one shirt with a 20% discount) 11.20x5=56 cost of all 5 shirts
- 4(1/2)x - (3/7) = (1/4)
- 4(1/2)x = (1/4) + (3/7)
- (9/2)x = (7+12)/28
-(9/2)x = 19/28
x = (19/28) * 2 / 9
x = (19/14) / 9
x = 19 / (14*9)
x = 19 / 126
