What is the solution of the following system?
use elimination method to figure it out
i dont know how to do that
do yo know how to do that?
sorry i was getting dinner
elimination -1 [ax - by = 1 ] ax + by = 1 -ax + by = -1 ax + by = 1 --------------- 0ax + 2by = 0 solve for one term first
-2 [ax - by = 1 ] < multiply them 2 ax + by = 1 < with any number as long as ^ ^ |____ |________ one term a or b is elminiated = 0 so you can you solve the equation
so do i times them both by 4 and -4?
first of all how do you solve an equation like this 2 = x + 2
uhhhh you minus 2 to both sides and x=0
correct you solve for x it is in the form x = number
what would i have to multiply to eliminate one of the terms (the column)
this is distributed _____________________ V V V -1 [ 2x - 2y = 2 ] 2x +2y = 1 ---- 0x --- 4 y = 1 solve for y y = 1/4 substitute what you got y = 1/4 2x + 2 (1/4) = 1 now you can solve
Is this supposed to be the answer to the problem ?
no it is an example
I thought you wrote the problem down wrong...my bad...sorry iforgot
I hope he knows about no solutions and infinite solutions
because one of them will apply here
