No. 1 = x
No. 2 = 2x+7
No. 3 = x-12
Answer:
x+(2x+7)+(x-12) = 131
From there you solve to get the numbers:
34, 75 and 22
Answer:
x = -6
Step-by-step explanation:
Step 1 :
Pulling out like terms :
1.1 Pull out like factors :
-2x - 12 = -2 • (x + 6)
Equation at the end of step 1 :
Step 2 :
Equations which are never true :
2.1 Solve : -2 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation :
2.2 Solve : x+6 = 0
Subtract 6 from both sides of the equation :
x = -6
One solution was found :
x = -6
