Solve the equation 13-2x=-7
2 answers:
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!
