What is the x-coordinate of the solution to the system of equations 3x-2y=-30 6x+3y=3

The x-coordinate of the solution is -4.

Step-by-step explanation:

The given system of equations have two equation.

                  ........ (1)

                    ...... (2)

Use elimination method to solve the equation (1) and (2).

Multiply equation (1) by 3.

                 ..... (3)

Multiply equation (2) by 2.

                  .....(4)

Add equation (3) and (4).

Divide both sides by 21.

Put this value in equation 1.

The solution of the system of equations is (-4,9). Therefore the x-coordinate of the solution is -4.

where are the choices?

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
