maths hw help?

I won't do all of them for you but will show you HOW to do the first one which will then help you to solve the rest:

10x+5=24

5 is on its own, meaning without x.

So you can subtract it from both sides: 10x+5-5=24-5 which then equals: 10x=19

You want x on its own now. Thus you divide 10 from each side: 10x/10=19/10

which then equals x=19/10=1.9

let me guess, your in a situation where you know the answer by doing it in your head but you don't know how to write it in the proper math syntax to be counted correct on the paper.

I'll give you the last one okay but you really gotta get this right because this operation is the basis for everything your going to do!!!

2x+5=23

2x=23+-5

2x=18

That covers the revers operation for addition and subtraction, now lets do the reverse operation for multiplication.

2x=18

2x/2 = 18/2

The 2 cancels out on the left side leaving just x

x=18/2

The rest here is just head work.

x=9

Do the rest of your homework please and learn this.

1.x=1.9

2.x=4

3.x=3

4.x=7

5.x=8

6.x=7

7.x=4

8.x=5

9.x=2

10.x=9
