Please help me write the equation for the problem below

1 answer:

8 0

Since you want both sides to equal each other, you can set up the following equation:

chess club members = computer club members

500 - 30x = 150 + 20x

x represents the amount of years that have passed. The coefficients for x represent the loss or gain of members per year.

Add 30x to both sides.

500 = 150 + 50x

Subtract 150 from both sides.

350 = 50x

Divide both sides by 50 to solve for x.

x = 7

It will take 7 years for both clubs to have the same amount of members.

What is the solution to y-2x=3 & 3x-2y=5

timofeeve [1]

Answer:

x= -11;y= -19

Step-by-step explanation:

lets name y-2x=3 "A" ;

name 3x-2y=5 "B".

2A: 2y-4x=6

2A+B: (2y-4x)+(3x-2y)=6+5

2y-4x+3x-2y=11

-x=11

so x= -11

so A is : y-2 (-11)=3

y+22=3

y= -19
