Question

2x+=2x+7 3x+18=5x+83

Plug a few points into the original equations and check to show that the system of equations has one solution. Explain your work.

Answer 1

We can first solve for x in one of the equations and then substitute into the other equation:

Equation 1:
2x+ = 2x + 7
=> x = -7

Now we can substitute x value we found into the second equation:

Equation 2:
3(-7) + 18 = 5(-7) + 83
=> -21 + 18 = -35 + 83
=> -3 = 48

This last equation is not true, and since we can't find a solution for x that satisfies both equations, the system of equations has no solution.
