Question

Which is the solution to the equation represented by the model below

Answer 1

c; x=2

Explanation:

You can see that there are 3 x's and 8 1's (3x+8), as well as 4 x's and 6 1's (4x+6).

The equation is 3x+8=4x+6

Subtract 3x and subtract 6: 2=x

Answer 2

Third option,
`x=2`

Explanation:

By observation, we can infer that

`3x+8=4x+6`.

Subtract 8 from both sides:

`3x+8-8=4x+6-8`

`3x=4x-2`

Subtract 4x from both sides:

`3x-4x=4x-2-4x`

`-x=-2`

Divide both sides by -1:

`(-x)/(-1)=(-2)/(-1)`

`x=2`
