Question

What is the value of the x variable in the solution to the following system of equations?
2x + 3y = 4
x - 2y = -5

Answer 1

i believe it would be -1

Answer 2

or 0

Answer 3

2x + 3y = 4

x - 2y = -5
x = -5 + 2y


2(-5 +2y) + 3y = 4
-10 + 4y +3y = 4
-10 +7y = 4
7y = 14
y = 2

2x + 6 = 4
2x = -2
x = -1


x - 4 = -5
x = -1

Answer 4

multiply 2nd equation with 2 and substract from 1st equation. then you will get
2y=14
y=7.
now put value of y in any eqn and solve for x
