Answer:

x=-1

Step-by-step explanation:

first you multiply 3 by whats in the parenthesis (you would get 6x-3)

then on the other side you combine like terms (add 7x plus 5x=12x)

Then you would isolate X to one side by subtracting 6x from 12x

Then you would subtract 3 from the side with 12x

By now your equation would be -6=6x

so you would divide both side by negative six to get x=-1

Answer:

x=-1

Step-by-step explanation:

3(2X-1)=5x+3+7x                  Distribute the 3 into the parenthesis

6x-3=5x+3+7x                      Isolate the x on one side

-6x     -6x

-3=5x+3+7x-6x

-3        -3

-6=5x+7x-6x                         Add all the x's

-6=6x                                    Divide 6 to isolate x

(-6)/6=(6x)/6

-1=x

Now you can check if it's right by inputting -1 for x and seeing if the equations equal each other

3(2(-1)-1)=5(-1)+3+7(-1)

3(-3)=-5+3-7

-9=-9                                   They equal each other so x=-1 is correct

If measure of angle 1 = 2x+6 and measure of angle 2 = 8x+4 where angles 1 and 2 are supplementary, then how much is the actual m
nlexa [21]

Answer:

The actual measure of ∠1 = 40°

Step-by-step explanation:

We are given: ∠1 = 2x+6 and ∠2 = 8x+4

and both angles are supplementary. we need to find the actual measure of ∠1

Supplementary angles: If the angles are supplementary their sum is equal to 180°

In our case ∠1 +∠2 = 180°

2x+6+8x+4=180

Solving the equation to find x, then we can find the actual measure of ∠1

2x+6+8x+4=180\\10x+10=180\\10x=180-10\\10x=170\\x=170/10\\x=17

So, value of x = 17

Now, finding actual measure of ∠1 by putting x=17 in equation 2x+6

\angle1=2(17)+6\\\angle1=34+6\\\angle1=40

So, the actual measure of ∠1 = 40°
