Question

If 49-X = 2, what does 7X equal?

Answer 1

329

Explanation:

49 - X = 2

find: 7X

49 - X = 2

49 - 2 = X

X = 47

substitute X=47 into 7X

• 7X
• 7 (47)
• 329

therefore, 7X = 329

Answer 2

7x = 42

Explanation:

This equation can be solved by isolating the variable.

Explanation:

To solve an equation like this, the first step is to isolate the variable. This means that we need to get x on one side of the equal sign by itself. This is the only way we can solve for x.

In this case, we isolate x by dividing both sides by seven.
