Answer:
29%
Step-by-step explanation:
I guarantee this is the right answer.
The answer would be the first phrase.
3x is 3 times x, and +4 is the sum of 3x and 4.
6x+4/5=8
subtract 6x from both sides
4/5=8-6x
multiply both sides by 5 to get rid of the fraction
4=40-30x
divide both sides by 2
2=20-15x
add 15x to both sides
15x+2=20
subtract 2 from both sides
15x=18
divide both sides by 15
x=1.2
