Answer:
Step-by-step explanation:
Answer:
x=3, y=1
Step-by-step explanation:
2x+3y=9. Equation 1
4x+y=13 Equation 2
y=13-4x. Modify equation 2 to isolate y
2x+3(13-4x)=9 subst value of y of equation 2 into equation 1
2x+39-12x=9 solve equation
-10x+39=9
-10x=-30
x=3
solve for y
2x+3y=9
2(3)+3y=9
6+3y=9
3y=3
y=1
Check answer:
4x+y=13
4(3)+1=13
13=13
