Question

(c) Solve the following inequation and represent its
solution on a number line:
2x
-1<7 +15 4, x el
​

Answer 1

Answer:

x∈ (-∞, 11.5)

Step-by-step explanation:

2x - 1 < 7 + 15

2x - 1 < 22

2x  < 22 + 1

2x < 23

x < 23/2

x < 11.5

x∈ (-∞, 11.5)

Draw a number line mark circle on 11.5 but don't fill it only circle then dark the line towards negative infinity
