Answer:
Step-by-step explanation:
It is 12 since 1/6=6^-1=6
implies 2*6=12
2x=1
10x+2=7
subtract 2 from both sides
10x=5
divide 10 on both sides
x=1/2, 0.5, or 5/10
Use 1/2 to solve '2x'
2*(1/2)=1
By multiplying both sides of an equation by a number, you can eliminate all decimals and fractions, so the answer is C.
It would be B. I took a test with this
