Answer:

Look in explanation

Step-by-step explanation:

I will assume that you're trying to solve for "x".

For number 1: 49+(5x+1) is a supplementary angle(180 degrees) so you can subtract 180-49 to get 131.

Now, 131 = 5x+1

        -1            -1

         130 = 5x

         /5      /5

Now, we isolate the x to get x=26.

Number 2: There is a supplementary angle as well so we can put 5x+12+6x+3=180.

Now, combine the like terms to get 11x+15=180 so we now isolate x.

                                                              -15   -15

                                                            11x=165

                                                            /11    /11

                                                               x=15

Now, try the rest and set the terms to 180.

5x+1+8+4x=180

2x+1+x-10=180

6+x+5x=180

x+2+153=180(This is similar to #1)

CHECK YOU ANSWERS BELOW AFTER YOU HAVE ATTEMPED THE REST OF THE PROBLEMS.

3. x=19

4. x=63

5. x=29

6. x=25

9 - 10x = 2x + 1 - 8x
Furkat [3]

Answer:

x=2

Step-by-step explanation:

9 - 10x = 2x + 1 - 8x

9-10x=-6x+1

Subtract 9 from both sides:

9-10x-9=-6x+1-9

-10x=-6x-8

Add 6x to both sides:

-10x+6x=-6x-8+6x

-4x=-8

Divide both sides by -4:

\frac{-4x}{-4}=\frac{-8}{-4}

x=2
