Weegy: 20x-11=5x+11
User: 7(x - 3) = 4(x + 5)
x = 1/11
x = 1/3
x = 41/11
x = 41/3
Weegy: -8
User: Solve for x.
7(x - 3) = 4(x + 5)
x = 1/11
x = 1/3
x = 41/11
x = 41/3
User: Solve the following equation.
x + 6 = x + x

User: An equation _____ has one solution.
always
sometimes
never
Weegy: It's either a trick question, [ or the person who wrote the question is guilty of fuzzy thinking.
a linear (1st order) equation will have one solution
a quadratic (2nd order) equation will have two solutions
a cubic (3rd order) equation will have three solutions
...
an nth order equation will have n solutions.
An equation may have more than one solution, or the solution(s) may be complex, rather than real, but it will always have one solution - and sometimes more than one.
Had the question been "An equation _____ has only one solution", the answer would have been #2, "sometimes". ]

14 + 8m = 14 - 3m - 5m
Ø
{0}
{all reals}
Weegy: Where are the following? These equation works out to zero.
User: Solution set: Ø
-2m + 5 = 2m + 5
-2m + 5 = -2m + 5
-2m + 5 = -2m - 5
Weegy: -2m + 5 = -2m + 5

7(x - 3) = 4(x + 5)
7x - 21 = 4x + 20
7x - 4x = 20 + 21
3x = 41
x = 41/3
