Question

WILL GIVE BRAINLIEST

Kisha and Rae are asked to solve −5x − 14 = 2x + 7. Identify where one of them made an error. Kisha Rae −5x − 14 = 2x + 7 −5x − 14 − 2x = 2x + 7 − 2x −7x − 14 = 7 −7x − 14 + 14 = 7 + 14 −7x = 21 Negative 7x over negative 7 equals 21 over negative 7 x = − 3 −5x − 14 = 2x + 7 −5x − 14 + 5x = 2x + 7 + 5x −14 = 7x + 7 −14 + 7 = 7x + 7 + 7 −7 = 7x negative 7 over 7 equals 7x over 7 x = − 1
Rae made the error when she added 7
Rae made the error when she added 5x
Kisha made the error when she subtracted 2x
Kisha made the error when she divided by −7

    I cant follow what you’ve written but here is the correct solution with steps:-

    -5x – 14 = 2x + 7

    -5x – 2x – 14 = 2x – 2x + 7

    -7x – 14 = 7

    -7x – 7 – 14 = 7 – 7

    -7x – 21 = 0

    -7x -21 + 21 = 21

    -7x = 21

    -7x/-7 = 21 /-7

    x = -3 answer

    The answer is A.

    Rae made the error when she added 7.

    The equation should be: -14 – 7 = 7x + 7 – 7
