Morgan made a mistake when subtracting the rational expressions below.
312-41 +12 + 2+ + 2 - 212-21 +3
t +3
t + 3
t +3
What was Morgan's error?
Morgan forgot to combine only like terms.
Morgan forgot to subtract the denominators as well
as the numerators.
Morgan forgot to cancel out the +3 in the numerator
and denominator as her final step.
Morgan forgot to distribute the negative sign to two of
the terms in the second expression.

Arrange the steps to solve this system of linear equations in the correct sequence. x + y = -2 2x – 3y = -9 tiles subtract 3x + 3y = -6 (obtained in step 1) from 2x – 3y = -9 (given) to solve for x. substitute the value of x in the first equation (x + y = -2) to get y = 1. the solution for the system of equations is (-3, 1). x = -15 the solution for the system of equations is (-15, 13). add 3x + 3y = -6 (obtained in step 1) to 2x – 3y = -9 (given), and solve for x. x = -3 substitute the value of x in the first equation (x + y = -2) to get y = 13. multiply the first equation by 3: 3(x + y) = 3(-2) 3x + 3y = -6.
