Answer:
x=-8
Step-by-step explanation:
-3(3x+8)+2=26-3x
We move all terms to the left:
-3(3x+8)+2-(26-3x)=0
We add all the numbers together, and all the variables
-3(3x+8)-(-3x+26)+2=0
We multiply parentheses
-9x-(-3x+26)-24+2=0
We get rid of parentheses
-9x+3x-26-24+2=0
We add all the numbers together, and all the variables
-6x-48=0
We move all terms containing x to the left, all other terms to the right
-6x=48
x=48/-6
x=-8

Step-by-step explanation:
simplify each equation and look for ones which solve to a simple numeric equality:
First equation solves to -3/7=-18/42...take a 6 from 18 and 42, and you get -3/7. -3/7=-3/7 which is true - that means that, no matter what value is inserted for x, a true equation will result = infinite number of solutions
Second equation simplifies to 3x=-30. Nope
Third equation simplifies to -18=-18 = infinite number of solutions
Fourth eq: 5=-7/2 = No solution
5th eq: 6.2x=-3.5-16.2 = nope
