Simplify. Thankyou! 1. -2(c + 2.5) - 5(1.2c + 4)

2. (m -3) - (-m + 12)

3. (-3x + 7) - (4x - 8)

4. -3(2y - 9) - (5y + 4)

1. -8c-25

2. 2m-15

3. 7x+15

4. -11y+23

Step-by-step explanation:

1. -2c-5-6c-20= -8c-25

2. m-3+m-12=2m-15

3. -3x+7-4x+8=-7x+15

4. -6y+27-5y-4=-11y+23

y=−9/2x+10

step-by-step explanation:

let's solve for y.

0−9x−2y=−20

step 1: add 9x to both sides.

−9x−2y+9x=−20+9x

−2y=9x−20

step 2: divide both sides by -2.

−2y

−2

=

9x−20

−2

y=

−9

2

x+10

i hope this is what you were looking for.
