Question

Write each subtraction equation as an addition equation.

1. a -9= 6
2. p - 20 = -30
3. 2 - (-12) = 15
4. X – (-7) = -10

Answer 1

9+6=?

-30+20=?

2+12=?

7x+-10=?

I'm not confident in the third one sryyy

Answer 2

a. a - 9 = 6

a + (-9) = 6 OR 6 + 9 = a

b. p - 20 = -30

p + (-20) = -30 OR -30 + 20 = p

c. z - (-12) = 15

z + 12 = 15 OR 15 + (-12) = z

d. x - (-7) = -10

x + 7 = -10 OR -10 + (-7) = x
