Question

2. 5x-15=2x-3
3. 4-x=6-3x
4.8+2x =13-x
5.2(x+3)=4x-10
tolong jawab pliss secepatnya

Answer 1

2. 5x - 15 = 2x - 3
5x - 2x = -3 + 15
3x = 12
x = 12/3
x = 4

3. 4 - x = 6 - 3x
4 - 6 = -3x + x
- 2 = -2x
x = -2/-2
x = 1

4. 8 + 2x = 13 - x
2x + x = 13 - 8
3x = 5
x = 5/3

5. 2(x + 3) = 4x - 10
2x + 6 = 4x - 10
2x - 4x = -10 - 6
-2x = -16
x = -16/-2
x = 8
