Does the system of equations have no solution, one solution or infinitely many solutions?

y=2 and y= -3

y= 1 and y= 1

y= -1 and y=2x+4

Reorder

Order the steps to show how to solve a linear system x = 5 and y = 2x + 3.

Substitute x = 5 into the equation y = 2x + 3.

The resulting equation is y = 2(5) + 3. Solve for y.

The value of y is 13

Write the solution as the point (5,13).

Multiple Choice
