Question

What is 2x + 4 < 16

Answer 1

Answer:

x<6         just letting you know that / is not meant for division it means a fraction bar

Step-by-step explanation:

1. Group all constants on the right side of the inequality

2x+4<16

Subtract  from both sides

(2x+4)-4<16-4

Simplify the arithmetic

2x<16-4

Simplify the arithmetic

2x<12

2. Isolate the x

2x<12

Divide both sides by 2

(2x)/2<12/2

Simplify the fraction

x<12/2

Find the greatest common factor of the numerator and denominator

x<6*2/1*2

Factor out and cancel the greatest common factor

x<6

3. Solution on a coordinate plane

Solution: x<6

Interval notation:

(-∞,6)
