3x=-26-8
3x=-34
3x/3=-34/3
x=-34/3 or -11.3
2x+5-10x+11=0
-8x=-11-5
-8x=-16
-8x/-8=-16/-8

5x+8-2x+26 = 3x + 34
2x+5-10x+11= -8x+16

since 2x+5-10x+11=0 then 8x=16 x=2
so the answer of the formula is 5x+8-2x+26=3x+34=3*2+34=40
the answer is 40

combining similar terms -8x + 16 = 0
-8x = -16
x= 2
simplify the second equation and substitute for the value of x
3x + 34 = 3(2) +34
= 6 + 34
= 40

5x+8-2x+26 (without an = this is not an equation all we can to is simplify)
3x+34
2x+5-10x+11=0
-8x+16=0
-8x+16-16=0-16
-8x+-16
-8x/-8=-16/-8
x=2

first one: (I am going to assume that equation equals zero)
5x+8-2x+26=0
consolidate like numbers
5x-2x+8+26=0
3x+34=0
get the x alone on one side
3x+34-34= 0-34
3x= -34
3x/3 = -34/3
x= 11.333333
Second one:
2x+5-10x+11=0
Consolidate like numbers
2x-10x+5+11=0
-8x+16=0
Get x alone on one side
-8x+8x+16=0+8x
16=8x
16/8= 8x/8
2=x
x=2

i dont know the first one because what is it suppose to equal to, unless you are suppose to put it in simplest form. If so, then it is 3x+34
for the second one:
2x+5-10x+11=0 write it out
-8x+16=0 combine like terms
-8x=-16 subract both sides
x=2 divide

The lower one, you just sum the x's together (2x-10x), then sum the integers (5+11), and then move the integers to the otehr side of the equation. Then divide whatever you get on the opposite side of the equation from "x" by the number of x's you have left.
The top one has no "=" sign in it so I assume you use the "x" value you get from the bottom and put it into the top, and "plug-n-chug"

the first one needs to equal something but the second one x = 2. it comes from combining the x terms on the left side to equal -8x and put the constant terms on the right side to equal -16 (-11-5=-16). then divide each side by -8 to get x = 2.
