3. 12 a
4. 7b-10
all you have to do is add up all of the sides.
You get: (1x20)/(5x20)=20/100=20%.
Hope i helped you! :)
Answer:
No solution
Explanation:
-4+19-7f = -15-7
cancel terms on both sides ( add 7f on both sides)
Calculate the sum
-4+19= -15
-4+19=15
15 = -15
The statement 15 = -15 is false so there is no solution :)
