Answer 4

okay so were trying to figure out what x equals here , give me a minute to solve this :)

Answer 5

Ok

Answer 6

Just help meh PLZ

Answer 7

so to solve it algebraically. we need to get x alone

since its adding we can subtract 6 from both sides
3x + (6-6) = (15-6)
3x = 9
then we can divide
9 ÷ 3 = 3

so x = 3
we can check by plugging it in the equation
3 x 3 + 6 = 15
9 + 6 = 15
15 = 15 !
so 3 is our answer
but i think since theres a question mark above the equal sign and it says "value substituted" it wants you to substitute what it says the value of x is in the equation and fill in the answers in that case is as simple as that
3 x 2 + 6 = 15
6 + 6 = 15
12 = 15 ... No ..

3 x 3 + 6 = 15
i did this above :) and yes it equals it
so i think they just want you to fill in the blanks there
but if not i showed you how to solve the algebra equation :)

Answer 8

sorry that took a while to type :P

Answer 9

It is a fill in the blank question

Answer 10

ah well then fill in the blanks!

Answer 11

I got 1 so how do I do the 2nd one?

Answer 12

On the paper do I put what you said in the 1st or 2nd part?

Answer 13

3 x 2 + 6 = 15
12 = 15

3 x 3 + 6 = 15
15 = 15
