The first step is to combine like terms. So u would do 2-6. You then get -4 then u just bring everything else down. So now u should have this :
8x -4 = 4x + 8 + 3x
Now you do the same thing to the other side. U combine like terms which in this case are 4x and 3x. So u just do 4+3 which is 7 so now u have 7x. So now ur equation would be:
8x -4 = 7x +8
Now u do the inverse of 7 which would be -7 and u do that on both sides. So it would look like this :
8x -4 = 7x + 8
-7x. -7x
So now 7 and -7 cancel each other other and 8 -7 is 1 so now u have one x. So ur equation would now look like this:
1x -4 = 8
Now u do the inverse of negative 4 which is +4. So you would add 4 on both sides on both sides. Like shown:
1x -4 = 8
+4 +4
So u just add 8 + 4 which is 12. Now since anything times 1 is itself ur answer will be X=12
Hope this helped
Set both angles equal to each other because they are vertical angles.
3x-3 = 2x + 13
3x-2x=13+3
1x =16
x=16
Answer:27
Step-by-step explanation:you want to divide 54 by 2 because 2 is 1/2
Answer:
43.92
Step-by-step explanation:
First you need the measure of angle C
180 - 90 - 37 = 53 degrees
Then use the Law of Sines with the pair you know:
sin 90 / 55 = sin 53 / x
Solve the equation
x * sin 90 / 55 = sin 53
x * sin 90 = 55 * sin 53
x = 55 * sin 53/sin 90
x = 43.92
