I need help with all the question

Answer 1

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
