3х + бу
бу =
18 and Зу = - 5х + 9
do these have one solution, ims, or no solution

The solution of the system of equations will be:

And the system of equations has ONLY ONE solution.

Step-by-step explanation:

Given the system of the equations

Arrange equation variables for elimination

so the system of the equations becomes

solve -21y = -63

subtract 90 from both sides

Divide both sides by 15

as

,

so, the system of equations contains only one solution.

Therefore, the solution of the system of equations will be:

And the system of equations has ONLY ONE solution.
