Select all the equations that have no solution. 1. 3x + 6 = 5 + 3x

2. -2(x - 3) = -2x + 6

3. 4 - 4x = 3x + 2

4. 4(x + 1) = 3(x + 2)

5. 5 - 3x = -3x + 4

7. if the value of x varies directly with the value of y, and x = 3 when y = 21. what is the valu y, and x = 3 when y = 21. what is the value of x when y = 105?

Which shows the correct solution of the equation 1/2a+2/3b=50, when b=30?

Give the functions f(x) = |x + 2| - 3, what is the domain? a, b,c, or d all real numbers x > 2 x < -2 all real numbers and x cannot equal to 2
