when solving for y, i need help with 2(y+5)=4x. i believe the answer is y=2x-5. can someone help?

2y + 10 = 4x
2y = 4x - 10
y = 2x - 5 (agrees with your suggested answer)

2(y+5)=4x
2y + 10 = 4x multiply
2y = 4x - 10 switch to the other side
y = 2x - 5 divided by 2
there u go

That is exactly correct!
2(y+5)=4x
(2(y+5))/2=(4x)/2
=
y+5=2x
y+5-5=2x-5
y=2x-5

Simplifying:
2*y + 10 = 4*x
2*y = 4*x - 10
y = 2*x - 5

2(y+5)=4x
2y + 10 = 4x
2y = 4x-10
y = 2x -5
Yes, your answer is surely, certainly, absolutely corrected.
Well done!!

lots of people will help
multiply 1/2 on both sides of your equation
gets rid of that 2 in front of (y+5) and makes 2x
now you have y + 5 = 2x
subtract 5 from both sides, gives y = 2x - 5
which is what you got.
good job!

2(y+5) = 4x
2y + 10 = 4x
2y = 4x - 10
y = 2x - 5
Trust your instincts!

2(y+5) = 4x
Divide everything by 2.
y + 5 = 2x
Subtract 5 from both sides.
y = 2x - 5
So. yeah. You were right.
