Question

The equation, and you have to find what he did wrong. Please help me, i'm stuck- ive been stuck on it since yesterday

Answer 1

9514 1404 393

Answer:

terms were improperly combined

Explanation:

I find the easiest way to identify the error in a solution is to solve it myself and compare with what is shown as being done.

Here, we're starting with ...

`(1)/(5)g-(1)/(10)-g+1(3)/(10)g-(1)/(10)`

If we identify the g-terms and the constant terms, we can group them the way Tyson did:

`(1)/(5)g+(-1)g+1(3)/(10)g-(1)/(10)-(1)/(10)`

The next step is to combine like terms. We can factor out g, so the coefficients are easier to see and combine.

`\left((1)/(5)+(-1)+1(3)/(10)\right)g-(1)/(10)-(1)/(10)\qquad\text{step 1a}\\\\(1)/(2)g-(1)/(5)\qquad\text{step 2}`

The error is 1 3/10 was combined with -2/10 as a constant instead of being combined with -4/5 as a coefficient of g.
