2x-6+(x/4)-3+90=180. solve for x and show work.

So you want to add lik terms first
group them together
I have gropued the like terms using brackets
[-2x+(x/4)]+[-6-3+90]=180
add lik terms
add the number terms
-6-3+90=81
[-2x+(x/4)]+[81]=180
subtract 81 from both sides
-2x+(x/4)=99
add 2x to both sides
x/4=99+2x
multipliy both sides by 4 to clear fraction
x=396+8x
subtract 8x from both sides
-7x=396
mulitply both sides by -1
7x=-396
divide both sides by 7
x=-396/7=-56 and 4/7

 1) Simplify brackets
−2x−6+  −3+90=180

2) Simplify −2x−6+x4−3+90 to −  −6−3+90
−  −6−3+90=180

3) Simplify - −6−3+90 to - +81
 - +81=180

4)Subtract 81 from both sides
-  = 180 - 81

5) Simplify 180−81 to 99
-  =99

6) Multiply both sides by 4
−7x=99×4

7) Simplify 99×4 to 396
−7x=396

8)  Divide both sides by −7
x=  

9) Simplify  to −
x= − 

ANSWER = −  

The coordinates of point a right now is (-3,-1) you have to multiply these coordinates by a factor of 2 to get (-6,-2)
