X/12=(2 1/3)/5 note that 2 1/3=7/3
x/12=(7/3)/5
x/12=7/15 multiply both sides by 12
x=84/15
x=28/5
x=56/10
x=5.6
Hello,
I suppose equations are:
x+y=3 (1)
x+2y=9 (2)
(2)-(1)==>y=6
(1)==>x=3-6
x=-3, y=6
Sol={(-3,6)}
34+56=90 this is your answer
Hope this helps lol
X=3.1:
Step-by-step explanation:
8x + y = 12 (substitute 3 for y)
<span>8x + 3 = 12 </span>
<span>8x = 9 </span>
<span>x = 9/8 </span>
<span>If y = 3 and 8x + y = 12, then x = 9/8.
HOPE THIS HELPS!!</span>
