(50 points + brainliest to correct answer)
arrange the steps to solve this system of linear equations in the correct sequence.
x + y = -2
2x – 3y = -9
a. subtract 3x + 3y = -6 (obtained in step 1) from
2x – 3y = -9 (given) to solve for x.
b. substitute the value of x in the first equation
(x + y = -2) to get y = 1.
c. the solution for the system of equations is (-3, 1).
x = -15
d. the solution for the system of equations is
(-15, 13).
e. add 3x + 3y = -6 (obtained in step 1) to
2x – 3y = -9 (given), and solve for x.
f. x = -3
g. substitute the value of x in the first equation
(x + y = -2) to get y = 13.
h. multiply the first equation by 3:
3(x + y) = 3(-2)
3x + 3y = -6.
basically put them in order : )
