Sagot :
Answer:
1. x = 3
2. x = 3
3. x > 1
4. x < 3
Solution:
1. 2x = 6
[tex]\frac{2x}{2}[/tex] = [tex]\frac{6}{2}[/tex]
x = 3
2. 2x + 2 = 8
2x = 8 -2
2x = 6
[tex]\frac{2x}{2}[/tex] = [tex]\frac{6}{2}[/tex]
x = 3
3. 5x > 5
[tex]\frac{5x}{5}[/tex] > [tex]\frac{5}{5}[/tex]
x > 1
4. 3x - 4 < 5
3x < 5 + 4
3x < 9
[tex]\frac{3x}{3}[/tex] < [tex]\frac{9}{3}[/tex]
x < 3
