Select all equations that have one solution. (4 x 8) = 18
X + X - (x + x) = 2 x - x + 2
-3(- x - 2) = 3( x - 2)
3(x) = x + 1
2 x + 2 x + 2 = 4 x + 2

answer: the first one

step-by-step explanation: use a calculator and divide the minutes by the dollars.

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square
