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
