Question

Solve the equation.

x – = 3

A.
x = –3

B.
x = –2

C.
x = 2

D.
x = 3

Answer 1

-x=3 is really -1*x=3
So what can you do to get X all alone on the left?

Answer 2

the question is X - 2 over 7= 3 what is X

Answer 3

OH

Answer 4

Okay, so the equation is \[\frac{ x-2 }{ 7 } = 3\]
First, how do we get rid of the fraction on the left?

Answer 5

add?

Answer 6

Unfortunately no... The operation to undo division is multiplication.

We need to multiply the left and right side by 7.

Answer 7

We would end up with:

\[x-2=3*7\]
\[3*7=21\]
Therefore...
\[x-2=21\]

Answer 8

What can we do to get X all by itself?

Answer 9

A. -3\[\frac{ 2 }{ 7 }\]

B-2\[\frac{ 5 }{ 7 }\]


C2\[\frac{ 5 }{ 7 }\]

D3\[\frac{ 2 }{ 7 }\]
