Question

A, 4x= -28

b, x- -6= -2
c, -x+= -9
d, -3x+7=1
e, 25x+-11= -86



2, here is an equation 2x+9= -15. write three different equations that have the same solution 2x+9= -15. show or explain how you found them.?
​

Answer 1

A. x = -7, B. x = -8, C. x = 9, D. x = 2, E. x = -3

Explanation:

A. 4x= -28

Divide both sides by 4.

`(4x)/(4\\)`=
`(-28)/(4)`. x= -7

B. x- -6= -2 -> x+6= -2

Subtraction 6 to both sides.

x- +6-6= -2-6, x= -8

C. -x+= -9 -> x= 9

D. -3x+7=1

Subtraction 7 to both sides.

-3x+7-7 =1-7 , -3x=-6

Divide both sides by -3.

`(-3x)/(-3)` =
`(-6)/(-3)`, x= 2

E. 25x+-11= -86 -> 25x-11= -86

Add 11 to both sides.

25x-11+11= -86+11, 25x= -75

Divide both sides by 25.

`(25x)/(25)` =
`(-75)/(25)`, x= -3

2. 2x+9= -15

Subtraction 9 to both sides.

2x+9-9= -15-9, 2x= -24

Divide both sides by 2.

`(2x)/(2)` =
`(24)/(2)` , x= 12

I don't think there's an answer.

I hope it helps you!
