Answer:

Y=-3/2

Step-by-step explanation:

-2y+3=-4y

Move constant to the right  by adding its opposite to both sides

-2y+3-3=-4y-3

Eliminate the opposites

-2y=-4y-3

collect the like terms

-2y+4y

collect the like terms

(-2+4)y

Calculate the sum

2y=-3

divide both sides of the equation by 2

2y÷2=-3÷2

Any expression divided by itself equal 1

y=-3÷2

y=-3/2

You would add -2y to -4y and get -6y then you would divide -6 and 3 and you would get 3/-6= -0.5 so. Y=-0.5 I hope this helped

you have a piece of wood that is 72 inches long u cut the wood into three pieces the second piece is 6 inches longer than the fi
tangare [24]

Let

x---------> the length of the first piece

y---------> the length of the second piece

z---------> the length of the third piece

we know that

x+y+z=72 -------> equation 1

y=x+6 -----> solve for x

x=y-6 -------> equation 2

z=6+y -------> equation 3

substitute equation 2 and equation 3 in equation 1

[y-6]+y+[6+y]=72

3y=72

y=(72/3)=24 in

<u>Find the value of x</u>

x=y-6 -------> equation 2

x=24-6=18 in

<u>Find the value of z</u>

z=6+y -------> equation 3

z=6+24=30 in

therefore

<u>the answer is</u>

the length of the first piece is 18 in

the length of the second piece 24 in

the length of the third piece is 30 in
