5. A student solved the following equation using the following steps:
2(2x+2)=4(x+4)
4x+4=4x+4
4=4
Infinitely many solutions
(2 points)
Based on the student's work, the equation was solved
incorrectly
The equation solved correctly would show that it has
one
solution(s). true or false
False
how many solutions does the equation have
The equation has infinitely many solutions.
that is not a answer choice
Apologies for the confusion. The equation has one solution.
7. Which equation has the same first step to solve as this equation: 2x+12−3x=27
(1 point)
Responses
4x−17+2x=9
4 x minus 17 plus 2 x is equal to 9
2x+12=27
2 x plus 12 is equal to 27
2x+12=−3x−27
2 x plus 12 is equal to negative 3 x minus 27
2(x−5)+2x=10
2x + 12 = 27
11. After combining like terms to simplify the equation 3−15x+24+16x=4x−24−4x
, what would be the next best step to finish solving?(1 point)
