Given:
y - x =13
17y + x = 11
Solve using elimination.
Solution:
In order to solve using elimination, we simply equate the two equations into one single solution.
y - x = 13
can be written as,
y - x -13 = 0
17y + x = 11
can be written as,
17y + x - 11 = 0
y - x - 13 = 17y + x - 11
Transpose y - x - 13 on the other side of the enequation, hence it must be taken to note that in transposing a number, the sign changes.
= 17y + x - 11 - y + x + 13
= 16y + 2x + 2
Final answer:
= 16y + 2x + 2
