Question

x + 2y = 3
3x - 2y = 5
.What is the solution to the system of equations?

A)
(4, 3.5)
B)
(2, 1/2)
C)
(2, -1)
D)
(1/2, 2)

Answer 1

Add both equations. Solve by elimination.

Answer 2

Add the two equations to get \(4x=8\), solve for x and substitute to get y.

Answer 3

You'll eliminate y, then solve for x. Substitute the value of x and solve for y.

Answer 4

x+2y=3
3x-y=5

Add both the equations
x+3x+2y-2y=3+5
2y cancels out
4x=8
x=4/8
x=2

Now put x =2 in first equation that is x+2y=3
2+2y=3
2y= 3-2
2y=1
y=1/2

therefore your answers are x=2 and y=1/2
