Question

Solve 2x+8<10 or 2x+8>20

Answer 1

Answer:

1 Add 88 to both sides.

2x=10+8

2x=10+8

2 Simplify 10+810+8 to 1818.

2x=18

2x=18

3 Divide both sides by 22.

x=\frac{18}{2}

x=

2

18

4 Simplify \frac{18}{2}

2

18

to 99.

x=9

x=9

Step-by-step explanation:

2x−8=10

1 Let x=9x=9.

2\times 9-8=10

2×9−8=10

2 Simplify 2\times 92×9 to 1818.

18-8=10

18−8=10

3 Simplify 18-818−8 to 1010.

10=10

10=10
