Answer: x=5
Step-by-step explanation:
2(3x−6)=12+6
Step 1: Simplify both sides of the equation.
2(3x−6)=12+6
(2)(3x)+(2)(−6)=12+6(Distribute)
6x+−12=12+6
6x−12=(12+6)(Combine Like Terms)
6x−12=18
6x−12=18
Step 2: Add 12 to both sides.
6x−12+12=18+12
6x=30
Step 3: Divide both sides by 6.
6x
6

Answer:
b = -10
Step-by-step explanation:
2(b + 3) = b – 4
2b + 6 = b - 4
-b -b
b + 6 = -4
-6 -6
b = -10

For this case we must give the result obtained by adding three times the number 15 with four times the number 2. For this we have, be "x" the result obtained when making the addition:
What is equivalent to:
Thus, the sum of three times 15 and four times 2 is 53.
Answer:
The sum of three times 15 and four times 2 is: 53.
