3 (x-1) - 8 = 4 (1+x) + 5. Too hard, i keep getting confused

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

One solution was found:

x = - 20

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation:

3 * (x-1) - 8 - (4 * (1+x) + 5) = 0

Step by step solution:

Step 1:

Equation at the end of step 1:

((3• (x-1)) - 8) - (4• (x+1) + 5) = 0

Step 2:

Equation at the end of step 2:

(3 • (x - 1) - 8) - (4x + 9) = 0

Step 3:

Step 4:

Pulling out like terms:

4.1 Pull out like factors:

-x - 20 = - 1 • (x + 20)

Equation at the end of step 4:

-x - 20 = 0

Step 5:

Solving a Single Variable Equation:

5.1 Solve : - x-20 = 0

Add 20 to both sides of the equation:

-x = 20

Multiply both sides of the equation by (-1) : x = - 20

One solution was found:

x = - 20

hope this is wht u wanted
