6x +12 - 3x = 70
Plz step by step
1 answer:
6x +12 - 3x = 70
6x-3x+12= 70
3x+12= 70
move +12 to the other side
sign changes from +12 to -12
3x+12-12=70-12
3x= 58
divide by 3 for both sides
3x/3=58/3
x=58/3 or x=19 1/3
Answer: x=58/3 or x=19 1/3

Step-by-step explanation:
amount of tax = $0.72
percent of tax= 6%
Let the original cost be x
so that
6% of x= 0.72
solve for x
6/100*x= 0.72
0.06x= 0.72
divide both sides by 0.06
x= 0.72/0.06
x=$12
Hence the cost is $12
