3x+y=8
y=8-3x
5x+3(8-3x)=8
5x+24-9x=8
-4x+24=8
-4x=-16
x=4
5x+3y=8
5(4)+3y=8
20+3y=8
3y=-12
Y=-4
5x+3y=8
5(4)+3(-4)=8
20+-12=8
8=8
Answer:
r = 15 1/6
Step-by-step explanation:
change every thing to have a 6 in the denominator
31/6 = 5 1/6
60/6 = 10
add the 31/6 to both sides to get the r by itself
60/6 + 31/6 = 91/6
r = 15 1/6
