Answer:

So, x= -1 ,y = -6 is the solution of system of equations.

Step-by-step explanation:

We have given system of equations :

2x - 3y = 16        (eq I)

5x -3y = 13         (eqII)

We have to solve the system of equations.

First, subtract the above equations to get value of x. we get,

2x - 3y = 16

-5x +3y = -13

_____________

-3x = 3

x = -1

Put this value of x in any above equations we get,

2(-1) - 3y = 16

-2-3y =16

-3y = 16 + 2

-3y = 18

y = -6

So, x= -1 ,y = -6 is the solution of system of equations.

Answer:

B.) two

Step-by-step explanation:

These equations have two solutions, one for solving for each variable. There is a solution for solving for x, and one for y. For both of these equations,

x = 5 -4y and y = 5/4 - x/4

Solve the equation, and check the solutions (√x+3)+6=3.
larisa86 [58]

Answer:

The equation has no solution.

Step-by-step explanation:

Hi there!

First, let´s write the equation:

(√x + 3) + 6 = 3

To solve the equation, let´s subtract 6 to both sides of the equation:

√x + 3 = -3

subtract 3 to both sides of the equation:

√x = -6  (the square root of any number can´t be negative, but let´s solve it anyway and then check the solution).

Square both sides of the equation:

x = 36

Now, let´s check the solution:

(√x + 3) + 6 = 3

x = 36

(√36 + 3) + 6 = 3

(6 + 3) + 6 = 3

9 + 6 = 3

15 ≠ 3

Then, the equation has no solution.

Have a nice day!
