"<span>The difference of six times a number and 7 is -49"...
In number and variables, this would be:
</span>

<span>
Add
7 to both sides.
</span>

<span>Simplify.

Divide both sides by
6.

Simplify.

Hope this helps.

For this, the equation is
90× 1.13³=y
X was replaced with y. Since she is gaining, you have to remember she is going to have 100 percent of what he had before, she will not lose any.
90× 1.13= 129.86
Now, we need to find the amount of interest she gained, so we have to subtract 90 from the total.
129.86-90=39.86
We can also find the answer by completing a small chart.
The first column will be the year. The second will be the amount. The third will be the interest for the year.
1 90 11.7
2 101.7 13.22
3 114.92 14.94
The total would round to 39.86, so her interest for the 3 year would be 39.86, with her having 129.86 altogether.
Simplify the <u>expression</u>.
