Help me please please help

1) 8y + 9         2) 2n + 4        3) 3d + 5h

rearrange the equations and combine like terms. combine the terms with the same variables and add / subtract them.

for example number 1:

9y - 11 + 20 - y

is the same thing as

<em>9y - y</em> <u>+ 20 - 11</u>

and now you can easily combine them:

<em>8y</em> + <u>9</u>

i hope this helps!

Solve the system of equations. <br> 3x-4y=8 <br> 18x-5y=10
ipn [44]

Answer:

y = -2    x = 0

Step-by-step explanation:

1. 3x-4y = 8

2. 18-5y = 10

Multiply equation 1 by 6

3. 18x-24y = 48

Subtract equation 2 from equation 3

4. -19y = 38

        y = 38/-19

        y = -2

Sub y = -2 back into equation 1

      3x-4(-2) = 8

      3x + 8 = 8

      3x = 0

      x = 0/3

      x = 0

I need help plez and thanks

He has a total of $58.19.
1 day = $2.74

58.19/2.74 
21.24

You can't have 21.2 days, so you need to round down to 21.

Jim can buy lunch for 21 days before he runs out of money on his account.
