Absolute Value Equation <br> | -4 + 5x |= 16 <br> Please show how to do the problem.
Gemiola [76]
If you have |a|=b, solve a=b and a=-b

so
|-4+5x|=16
so solve
-4+5x=16 and -4+5x=-16
add 4 to both sides
5x=20 and 5x=-12
divide both sides by 5
x=4 and x=-12/5

the 2 solutions are x=-12/5 and x=4

the difference between two numbers is 9. three times the smaller is equal to twice the larger. what are the numbers?
Sergio039 [100]

Answer: 27 and 18

Step-by-step explanation:

x - y = 9  → x = 9 + y

3y = 2x

3y = 2(9 + y)

3y = 18 + 2y

3y - 2y = 18

y = 18

2x = 3(18)

2x = 54

x = 27

x - y = 9

27 - 18 = 9

9 = 9
