Question

3x + y =10
x - y =2
what is the solution

Answer 1

Answer:

answer is x= 3 y=1

Step-by-step explanation:

3x + y = 10_(1)

x-y = 2 _(2)

multiply EQ 2 by 3

3x - 3y = 6 _(3)

from EQ 1 and 2

by using Elemination method

3x + y = 10

3x - 3y = 6

- + -

4y = 4

hence y = 1

substituting value of y we get

y = 1

x = 3
