Answer:x=-1
Step-by-step explanation:Step by step solution :
Step 1 :
Equation at the end of step 1 :
8 • (2x + 9) - 56 = 0
Step 2 :
Step 3 :
Pulling out like terms :
3.1 Pull out like factors :
16x + 16 = 16 • (x + 1)
Equation at the end of step 3 :
16 • (x + 1) = 0
Step 4 :
Equations which are never true :
4.1 Solve : 16 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation :
4.2 Solve : x+1 = 0
Subtract 1 from both sides of the equation :
x = -1
One solution was found :
x = -1
