Let's simplify each equation:
Equation 1:
6x + 12 = 6(x + 2)
6x + 12 = 6x + 12
-6x + 6x = 12 - 12
0 = 0
Equation 2:
2x + 6 = 3x + 2
2x - 3x = 2 - 6
-x = -4
x = 4
Equation 3:
9x + 3 = 9x - 9
-9 + 9x - 9x = -3
0 = -3
There is no solution for this equation.
Equation 4:
3(x + 1) = 3x
3x + 3 = 3x
3 = 0
There is no solution for this equation.
Therefore, the equation that has exactly one solution is Equation 2: 2x + 6 = 3x + 2.
Which equation has exactly one solution? This question requires you to show your work. (1 point) Responses 6x+12=6(x+2) 6 x plus 12 is equal to 6 times open paren x plus 2 close paren 2x+6=3x+2 2 x plus 6 is equal to 3 x plus 2 9x+3=9x−9 9 x plus 3 is equal to 9 x minus 9 3(x+1)=3x
