Question

1. Solve each equation. a. 4x = -28 b. x - -6 = -2 C.-Y + 4 = -9 d. -3x + 7 = 1 e 25% -11 = -86​

Answer 1

A,-7

B, 4

C,13

D,2

Explanation:

A,Step 1: Divide both sides by 4.

`(4x)/(4) = ( - 28)/(4)`

`x = - 7`

B,Step 1: Add 6 to both sides.

x−6+6=−2+6

x = 4

C, Step 1: Regroup terms.

4−Y=−9

Step 2: Subtract 44 from both sides.

-Y=-9-4−Y=−9−4

Step 3:Simplify -9-4−9−4 to -13−13.

`( - y)/(1) = ( - 13)/( - 1)`

Y = 13

D,Subtract 77 from both sides.

-3x=1-7−3x=1−7

2, Simplify 1-71−7 to -6−6.

-3x=-6−3x=−6

3,Divide both sides by −3.

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

4,Two negatives make a positive.

x = 6/3

x = 2.
