1st the sum of y and 8 is
y+8
the quotient of 50 and (y+8) is simply dividing 50 by (y+8)
50 / (y+8)
Twice the quotient mean multiply 50 / (y+8) by 2, so the answer is:
2 * 50 / (y+8)

3x+3=3y 2x-6y=2 (Solving Systems Of Linear Equations By Elimination)

Sergio [31]

3x+3=3y ⇒ 3y-3x=3 ⇒3(y-x)=3 ⇒ y-x=1
2x-6y=2 ⇒ 2(x-3y)=2 ⇒ x-3y=1

We must to collect two equations.
x's is lost;
y-3y=2
-2y=2
y=-1 ; x-3.(-1)=1 ⇒ x=-2

Answer is (-2,-1)
