Find the solution to the system of equations given below using elimination by addition.
5x + 2y = -45
5x + 8y = -15
:
Multiply the 1st equation by -1, results
Find the solution to the system of equations given below using elimination by addition.
-5x - 2y = +45
5x + 8y = -15
------------------adding eliminates x, find y
0x + 6y = 30
x =
x = 5
:
I'll let you find y using substitution in one of the original equations
Check it in the other original equation
