Answer:

2y +12

Step-by-step explanation:

(4y + 3) - (2y - 9)

Expand

- (2y - 9) =  - 2y + 9

4y + 3 - 2y + 9

Group like terms and simplify

4y - 2y + 3 + 9 \\ 2y + 12

Hey there! I'm happy to help!

First, we subtract the variables.

4y-2y=2y

And we subtract the constants.

3--9

3+9=12

So, the difference is 2y+12.

Have a wonderful day! :D

Find the solution of the system of equations.<br><br> 15x -4y = -50<br><br> 3x - 2y = -16
Fittoniya [83]

Answer:

15x - 4y =-50 -----(i)

3x - 2y=-16 --------(ii)

Using Substitution

From (i)

15x=4y-50

x=4y-50/15

Substitute x=4y-50/[15] into eqn (ii)

3x - 2y= -16

3[4y-50]/15 - 2y =-16

Multiply through by 15 to clear the fraction

3(4y - 50) - 30y=-240

12y - 150 -30y=-240

12y-30y=-240+150

-18y = -90

y=90/18

y=5.

Substitute into any eqn of choice to get x

3x - 2y=-16

3x - 2(5)=-16

3x - 10=-16

3x=-16+10

3x=-6

x=-6/3

x=-2.

x= -2

y=5
