Answer:
x=23/8 or 2.875
Step-by-step explanation:
To solve this question you have to first subtract 7 from both sides resulting in:
8(x)=23
Then divide both sides by 8 resulting in:
x=23/8 or 2.875
Step-by-step explanation:
Multiply by the reciprocal, also sometimes referred to as "Keep, Change, Flip." Here is how it works. You rewrite the division question as a multiplication question by flipping the second fraction over. Next, keep the first number, change the division to multiplication and then flip the second fraction over.
1/4x-5=10
First we need to cancel out the fraction, so we will multiply everything by 4.
x-20=40
Now we would add the twenty to the forty
x=60
I hope that this helps:)
