3. -x + 2 = 5
4. x + 4 = 6
5. 11 = 3 + 4x

i need help on these two step equations! please step by step! please and thank you!

Answer 1

1.) x = -2 2.) x = -4 3.) x = -3 4.) x = 2 5.) x=2

Explanation:

1. Subtract 5 from both sides.

-4x=13-5

Simplify 13 - 5 to 8

-4x = 8

Divide both sides by -4

x=-8/4

Simplify 8/4 to 2

x= -2

2. Subtract 4 from both sides.

-2x=12-4

Simplify 12-4 to 8.

-2x=8

Divide both sides by −2.

x= -8/2

Simplify 8/2 to 4.

x=-4

3.Regroup terms.

2-x=5

Subtract 2 from both sides.

-x=5-2

Simplify 5-2 to 3.

-x=3

Multiply both sides by −1.

x=-3

4.Subtract 4 from both sides.

x=6-4

Simplify 6-4 to 2.

x=2

5.Subtract 3 from both sides.

11-3=4x

Simplify 11-3 to 8.

8=4x

Divide both sides by 4.

8/4=x

Simplify 8/4 to 2.

2=x

Switch sides.

x=2
