Answer:
Step-by-step explanation:
1. x + 5.3 = 10.1
combine the like terms
x = 10.1 - 5.3
x = 4.8
2. x - 4.2 = 12.9
combine the like terms
x = 12.9 + 4.2
x = 17.1
3. 1.5x = 60
divide both sides by 1.5
x = 60/1.5
x = 40
4. x/1.3 = 1.8
cross multiply
1.3 goes to 1.8 and x stands alone
x = 2.34
Hope this helps
