Question

10x-7=7+5 find the value of x

Answer 1

In order to find the value for x you need to get it alone one side of the equation

We can do this by adding, subtracting, multiplying or dividing. Whatever we do to one side of the equation we must also do to the other

10x-7=7+5

First let's siplify this by adding the 7 and the 5 on the right side of the equation together. We can do this because they are like terms. 7 plus 5 is 12 so we can rewrite this as:

10x-7=12

+7        +7

add 7 to both sides of the equation which gets rid of the -7 on the left side

10x = 19

------   -----

 10      10

Divide both sides of the equation by 10 to get x alone on the left side.

x=19/10

Most likely you would leave the answer the way it is in fraction form but you can also express this as a mixed number 1 and 9/10ths

or as a decimal 1.9

Answer 2

No im asking the question, not answering. :l

Answer 3

How do you solve this?  mx+nx=40

Answer 4

Find the counterexample for this equation. If|x| =7, then x=7

Answer 5

10x-7=7+5

10x = 7+5+7

10x = 19

x = 1 9/10

Answer 6

4x + 2y +z = 10

-6x -y - 5z = -34

3x + 3y + 6z = 9

Answer 7

one point nine

Answer 8

2c-5=9 equations C=7

Answer 9

10x-7= 7+5

10x-7= 12

10x-7+7= 12+7

10x= 19

10x/10= 19/10

x= 1.9
