Question

(4,3) is a solution to the following system of equations: 2x+ y = 11

y=x-1
True or False

Answer 1

True

Explanation:

Substitute the x and y values of the point into the first equation and the x value of the point into the second equation. If both equations are satisfied then the point is a solution.

2(4) + 3 = 8 + 3 = 11 ← True

y = 4 - 1 = 3 ← True

Thus (4, 3 ) is a solution to the system of equations.
