2x + 4y = 14 and 3x - 4y = -39

x = 1 y= 3

Step-by-step explanation:

Multiply each equation by the value that makes the coefficients of y opposite.

Simplify.

Add the two equations together to eliminate y from the system.

Divide each term by 8 and simplify.

Substitute the value found for x into one of the original equations, then solve for y.

The result can be shown in multiple forms.

Point Form:

(1,3)

Equation Form:

x=1 ,y=3

.

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
