Can some one help me plz I really need help

1. 2x + 50 = 100
subtract 50 on both sides and then divide by 2.

x = 25

180 - 100 = 80

m
2. 7x - 4 = 87
add 4 on both sides and divide by 7.

x = 13

180 - 87 = 93

m
3. 5x - 2 = 38
add both sides by 2 and divide by 5.

x = 8

180 - 38 = 142

m
4. 14 + 6x = 134
subtract both sides by 14 and divide by 6.

x = 20

180 - 134 = 46

m
5. x = 53

m
6. x = 14
