Step-by-step explanation: When you are asked to solve an inequality like the one in this problem, your goal is the same as it is when solving equations which is to get x by itself on one side.

In this problem, since x is being multiplied by 3 on the left side of the inequality, to get x by itself, we divide both sides by 3.

On the left side, the 3's cancel and we're left with x. On the right side, 12 divided by 3 is 4 so we have X > 4.

This means that A would be or answer.

For what value of the variable will b the value of 3−5c be 1 less than the value of 1−c?

Crank

Answer:

c = 3/4

Step-by-step explanation:

Lets set up an equation.

You can get

3-5c + 1 = 1-c to show that it is one less.

now we can solve it.

So by combining like terms, we get:

4-5c = 1-c

that then becomes:

3-5c = -c

--> 3 = 4c

--> c = 3/4
