Question

Solve the system using elimination. 3x - 5y = 8 X - 5y = - 4

Answer 1

Answer::.x=6,y=2

3x - 5y = 8......(1)

X - 5y = - 4......(2)

subtracting equation 2 from 1 we get

Step-by-step explanation:

3x - 5y = 8

X - 5y = - 4

-

------------------

2x=12

x=12/2=6

multiplying equation 2 by3 weget

3x-15y=-12........(3)

subtracting equation 1from 3

3x-15y=-12

3x-5y=8

------------------

-10y=-12-8

y=-20/-10=2
