Solve the equation 13-2x=-7

Mathematics

patriot [66]3 years ago

Subtract 13 from both sides.

-13
-7 = -20

-2x = -20

Divide by 2 on both sides.
Remember: Negative divided by a negative makes a positive.

-2/-2 = 1
-20/-2 = 10

Your answer:
x = 10

▶13 - 2(x) - -7 = ?
? = 0

▶20 - 2(x)
Two is a negative
So, -2 = ?
Remember, that I said the mysterious number is '0' until we get to the REAL answer!

▶ (x) - 10 = 0
If we 'add' from your side we will get your result!

▶We have One Solution in this problem◀

⚠So, lets test it out⚠

✔ x - 10 = 0
+10
-------
✔10✔


▶✅x = 10✅
