Question

15(2 x+3)+100=110-5x

30 x+45+100=110-5x
30 x+145=110-5x
35 x+145=110
35 x=-35
x=-1

Answer 1

Explanation:

Reasons for each step

1. Distribute: 15(2x + 3) = 30x + 45

2. Combine Like Terms: 45+100 = 145

3. Addition Property of Equality: 30x+5x+145 = 110-5x+5x => 35x+145 = 110

4. Subtraction Property of Equality: 35x+145-145 = 110-145 => 35x = -35

5. Division Property of Equality: 35x/35 = -35/35 => x = -1
