no solution one solution infinitely many solutions
3x + 7 = 14 + 3x
22x + 11 = 4x - 7
3(x + 2) = 3x + 6
Part 1
we have
3x + 7 = 14 + 3x
solve for x
3x-3x=14-7
0=7 -----> is not true
that means
No solution
Part 2
we have
22x + 11 = 4x - 7
solve for x
22x-4x=-7-11
18x=-18
x=-1
so
One solution
Part 3
we have
3(x + 2) = 3x + 6
solve for x
Divide by 3 both sides
x+2=x+2 -----> its a identity
that means
infinitely many solutions
