Question

Rodney is given two linear equations: x – y = 11 and 2x + y = 19. What value of x should he get as a solution for this system of linear equations?
a.3/41
b.9
c.10
d.41/3

Answer 1

This problem is well suited for the use of the "elimination method" further they only want the x value so eliminate the y. this can easily be accomplished by adding the two equations.

Answer 2

You have to use"Simultaneous equations"
Noe you can do both ways here, either Elimination or substitution.

Answer 3

Simply add them, the y will be eliminated and solve for x.

Answer 4

Do the addition
