Answer: X=4
Step-by-step explanation:
Pulling out like terms :
1.1 Pull out like factors :
2x - 8 = 2 • (x - 4)
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-4 = 0
Add 4 to both sides of the equation :
x = 4
One solution was found :
x = 4
3+9=12

red + blue = 39
there are 9 red marbles and 30 blue marbles
green marbles = 30 * 4 / 10 = 12
Step-by-step explanation:
Answer:
2(x-3)(x+2)
Step-by-step explanation:
2x^2 - 2x - 12
2(x^2 - x -6)
2(x^2 - 3x + 2x - 6)
2(x(x - 3) + 2(x - 3))
2(x-3)(x+2)
Answer:
3
Step-by-step explanation:
Given the 2 equations
2x + 3y = 9 → (1)
- 2x + 2y = 6 → (2)
Adding the 2 equations term by term will eliminate x
(2x - 2x) + (3y + 2y) = (9 + 6), that is
5y = 15 ( divide both sides by 5 )
y = 3
