Question

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

Answer 1

 1) Simplify brackets
−2x−6+ $\frac{x}{4}$ −3+90=180

2) Simplify −2x−6+x4−3+90 to − $\frac{7x}{4}$ −6−3+90
− $\frac{7x}{4}$ −6−3+90=180

3) Simplify - $\frac{7x}{4}$−6−3+90 to - $\frac{7x}{4}$+81
 - $\frac{7x}{4}$+81=180

4)Subtract 81 from both sides
- $\frac{7x}{4}$ = 180 - 81

5) Simplify 180−81 to 99
- $\frac{7x}{4}$ =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= $\frac{396}{-7}$ 

9) Simplify $\frac{396}{-7}$ to −$\frac{396}{7}$
x= −$\frac{396}{7}$ 

ANSWER = −$\frac{396}{7}$  

Answer 2

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
