x = −2
x = 2
x = 13

Answer 1

am i right with A?

Answer 2

Answer 3

i am assuming equation is \( \frac{2x-20}{3}=2x\) as \( 2x\:-\frac{\:20}{3}=\:2x \) would not have a solution

you can multiply both sides by 3 to get rid of the fraction: \( \frac{2x-20}{3}\cdot \:3=2x\cdot \:3 \ \ \therefore \ \ 2x-20=6x\)

take the \( '+20'\) to th other side: \( 2x=6x+20 \) and then so the same with the variables which inculde `x`: \( 2x-6x=6x+20-6x \implies -4x=20\)

finally, divide by \(-4\) and ultimately, you will get \( \boxed{x=-5} \)

Thank you for this explanation!
