Answer: 11/3 or 3 2/3
Step-by-step explanation:
Simple to do this as the 11 and 15 can be simplified as 1 goes in 11... 11 times and 5 goes into 15... 3 times. Thus 11/3.
Solve for A:3 + 5/a = 3/A - 2
3 + 5/a = 3/A - 2 is equivalent to 3/A - 2 = 3 + 5/a:3/A - 2 = 3 + 5/a
Bring 3/A - 2 together using the common denominator A:(3 - 2 A)/A = 3 + 5/a
Multiply both sides by A:3 - 2 A = A (3 + 5/a)
Subtract (3 + 5/a) A + 3 from both sides:A (-5/a - 5) = -3
Divide both sides by -5/a - 5:Answer: A = 3/(5 + 5/a)
<span>2x+3y=11
Y= -2x + 1 re-write -2x - y = -1
so
</span>2x + 3y =11
-2x - y = -1
--------------add
2y = 10
y = 5
<span>Y= -2x + 1
</span>5 = -2x + 1
-2x = 4
x = -2
answer
solution (-2 ,5)
