Answer:
Step-by-step explanation:
Here is the workings
2x+4y+6+2y-5+3x combine like terms
2x+3x+4y+2y+6-5
Step 2
2x+3x+4y+2y+6-5 Add the similar exponents
5x+4y+2y+6-5
5x+6y+6-5
Step 3
5x+6y+6-5 Add and subtract
Your answer would be 5x+6y+1
I wish i could show u how to work it out but just do it or work it out the same way as the fractional numbers.
Answer:

_________________


<u>Remove the parentheses:</u>

<u>Combine like terms:</u>


<u>Multiply 3 and 5x = 15x:-</u>

<u>Combine like terms:</u>


<u>Expand: 3x-(2x-1)= x+1</u>

<u>Subtract 1 from both sides:</u>


<u>Add 9x to both sides:</u>


<u>Divide both sides by 10:</u>

I believe the answer is 311.157055138. That is if i did my math correctly. I hope this helps. Good luck!
2x+4y=0
substitute y with 0
2x+4(0)=0
solve the equation
2x+0=0
2x=0
divide by 2 on both sides
x=0
4x+8y=7
substitute y with 0
4x+8(0)=7
solve the equation
4x+0=7
4x=7
divide by 4 on both sides
x=7/4 or x=1 3/4 or x=1.75
3x-7y=-29
2x+2y=6
solve the bottom equation
3x-7y=-29
x=3-y
substitute for x
3(3-y)-7y=-29
solve the equation
y=19/5
now substitute for y
x=3-
solve for x
x=-4/5
the possible solution of the system is the ordered pair
(x,y)=(
)
