7x - 3(-2) = 23
7x - - 6 = 23 (two minuses make a plus)
so it’s gonna be 7x + 6 = 23
Now you have isolate you x, so move everything else to the other side, but remember to change your sign when transferring to the other side
7x = 23 - 6
7x = 17
To isolate x in this multiple, you divide by 7 (because the inverse of multiplication is division)
x = 17/7
Answer:I would add 3x on both sides because it would allow you to have a positive variable saving you time and effort.
Step-by-step explanation:7=7x-9
So i think u subtract how much money the person got and then subtract the answer by his pay.
Whatever% of anything is just (whatever/100) * anything.
now, we know Trever makes $500 in salary and 2% on sales, let's say he sells "x" amount, how much is 2% of x? well (2/100) * x, or 0.02x.
Therefore Trever's earnings are 500 + 0.02x, his salary plus his commission.
to earn a total of 2,000, then 500 + 0.02x = 2000, thus
2(x+7)^2=0 would be your answer :)
