Question

Solve for x: the quantity of x plus 20 over 2 = 3x

x = 10

x = 4

x = -14

x = -17

Answer 1

Im assuming its written out like this... \[x +(20\div2)\] right?

Answer 2

yes

Answer 3

ok, so first we have to get x on one side of the equation so i would subract x from both sides and get \[20\div2= 2x\]

Answer 4

next i would simplify \[20\div2\] by simply dividing it, so 10 now divide out the 2 from x. So for your final answer you get 5

Answer 5

All your answers you posted for the answer to the equation seem to be wrong

Answer 6

Ive checked to make sure also.

Answer 7

it's probably
\[ \frac{x+20}{2}= 3x \]

Answer 8

aww good point phi

Answer 9

in that case the answer would be x=4

Answer 10
