Question

3(x - 1) - 8 = 4(1+x) + 5​

Answer 1

x = -20

Explanation:

3(x - 1) - 8 = 4(1+x) + 5​

3x - 3 -8 = 4 + 4x + 5

3x - 11 = 9 + 4x

-x = 20

x = -20

Answer 2

x= 20

Explanation:

Step 1- Distribute into the parenthesis.

3x-1(3)-8= 1(4)+4x+5

Step 2- Multiply

3x-3-8= 4+4x+5

Step 3- Add.

3x-3-8= 4x+9

Step 4- Subtract 3x to both sides to move the variable to one side.

3x-11= 4x+9

-3x -3x

Step 5- Subtract 9 to both sides.

-11= 1x+9

-9 -9

-20= x

Exchange the signs.

20= x
