What’s 5+5? I really don’t know!

55! <if you really don't know is 10>

Step-by-step explanation:

if you take 5 and put it next to 5 you get 55

<if you really don't know you get 10>

5+5=10 and if its difficult that way you can go back to your multiplication table which says 5×2 or 2×5 which ever way is 10

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3
