How do you solve #3v+5-7v+18=17#?

Answer 1

We want to have all the terms involving #v# on one side, and all the known numbers on the other side.

To do so, begin with subtracting 18 from both sides: #3v+5−7v+18-18=17-18#, which yields #3v+5−7v=-1#

Then, subtract 5 from both sides: #3v+5−7v-5=-1-5#, which yields #3v−7v=-6#

Now we compute #3v-7v= v(3-7)=-4v#

We have finally reached the form #-4v=-6#, which means that we have all terms involving the variable #v# on the left and all known numbers on the right.

We can divide by 4 on both sides, and get #-v=-\frac{6}{4}=-\frac{3}{2}# and finally deduct #v=\frac{3}{2}#.

To solve the equation 3v + 5 - 7v + 18 = 17, you first need to combine like terms. Group the v terms together and the constants together. Then, simplify the expression. After that, isolate the variable v by adding or subtracting constants from both sides of the equation. Finally, solve for v to find its value.

Answer from HIX Tutor

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
