Question

Solve for x and y using elimination method: x + 2y = 5; 3x + 3y = 10​

Answer 1

Step-by-step explanation:

1. mulyipying eq 1 by 3

we get

3x+6y=15.......(eq3)

-eq3from eq2

3x+6y=15

- 3x+3y=10

__________

00+3y=5

y=5/3

substituting y=5/3 in eq 1

X+2y=5

X +2(5/3)=5

X+10/3=5

X=10/3+5

X=10+15/3

X=25/3

therefore x=25/3,y=5/3
