Question

2x + 3y = -4

x - 2y = 5
Question 1 answers
x = 1, y = -2
x = -1, y = 2
x = 1, y = 2
x = -2, y = -1

Answer 1

x = 5 + 2y

2x + 3y = -4

Substitute 5 + 2y for x in second equation and solve for y. Insert that value into the first equation and solve for x. Check by inserting both values into the second equation.
