Sarah's answer was incorrect.
In Sarah's step, she made an error in subtracting 33 from both sides of the equation. It should have been:
5x + 3 = 9x - 33
36 = 4x
But then she divided 36 by 4 to solve for x, which is incorrect. The correct step would be to divide both sides of the equation by 4:
36/4 = 4x/4
9 = x
sarah and jose were trying to solve the problem below. which one was incorrect and why? (it shows their responses step-by-step)
there is an image of two parallel lines and a transversal, both angles are same side interior, one angle is (5x+3) degrees and the other angle is (9x+33) degrees, both of these angles are supplementary
jose's answer:
5x+3+9x-33=180
14x-30=180
14x=210
x=15
sarah's answer:
5x+3 = 9x-33
3 = 4x-33
36 = 4x
9 = x
