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.
