9. Write the statement for 8u = 6 + 8.
10. Remove two of these matchsticks to make the valid equation.
IX - V1= V

Answer 1

Answer:

1. equation

2. 3z+3w=24

3.12 is subtracted from x equals 13

4. sorry I don't know

5.unknown

6. 2x+x=81

7. 20+x =45

8. 1/3x+x=10

9.u is multiplied by 8 gives 6+8

10.X-V=V

hope it helps you
