Question

Can you show me step by step on how to solve x+7>11

Answer 1

x>4

Explanation:

what you would do first is move the 7 to the other side of the sign and do 11-7 which equals 4. Next since x has no number with it and it is positive you would do 4 divided by 1 which means x is greater than 4. Thus your answer is x>4

Answer 2

9514 1404 393

Answer:

x > 4

Explanation:

Step 1. Locate the variable.

It is on the left side only.

Step 2. Identify any other terms on the same side of the equation as the variable.

+7 is a term there

Step 3. Add the opposite of that term to both sides of the inequality. (This is the "work." The previous two steps are observation: looking to see what you are working with. You should always start by doing that.)

x +7 -7 > 11 -7

x > 4 . . . . . . . . . . simplify (collect terms)

The solution is x > 4.

Additional comment

This is a "one-step" inequality, because all we had to do was add -7. If there is a coefficient on the variable, it is a 2-step inequality. If there are variables on both sides of the comparison symbol, then more steps may be required.
