If you would like to know the equality of the expression 4 * x/5 - 2 * x/5, you can calculate this using the following steps:
<span>4 * x/5 - 2 * x/5 = (4 - 2) * x/5 = 2 * x/5
</span>
The correct result is 2 * x/5, which is none of the results written above.
<span>9g - 10 = 6g + 8 + 9
</span>
To begin, simplify like terms on each side:
9g - 10 = 6g + 17
Next, you can isolate the variable by adding 10 to each side:
9g = 6g + 27
Subtract 6g from each side:
3g = 27
Finally, divide each side by 3:
g = 9
