i’m pretty sure no ones gonna help w all 21 questions but i’ll do one or two to help you get started
1. 4t + 13 = 5
step 1. subtract 13 from both sides
4t + 13 = 5
- 13 -13
4t = -8
step 2. divide 4 on both sides to get T alone
4t = -8
— —
4 4
t = -2
2. 6.3 = 2x - 4.5
step 1. Add 4.5 on both sides
6.3 = 2x - 4.5
+ 4.5 +4.5
10.8 = 2x
step 2. divide by 2 on both sides to get x alone
10.8 = 2x
—— ——
2 2
5.4 = x
hope these examples help
