1 answer:
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)
