The solution of the equation 9x=7(x+2) is:
Option D) 7
Step-by-step explanation:
9x=7(x+2)
Eliminating the parentheses applying distributive property:
9x=7(x)+7(2)
Multiplying:
9x=7x+14
Grouping the x's on the left side of the equation: Subtracting 7x both sides of the equation:
9x-7x=7x+14-7x
Subtracting:
2x=14
Solving for x: Dividing both sides of the equation by 2:
2x/2=14/2
Dividing:
x=7
Solution: x=7 (option D)
The -9 stays the same the whole time but the other number being multiplied decreases by one each layer, so the next three would be:
-9 x -1 = 9
^^^ -1 is in the second multiplication slot bc 0 - 1 = -1
-9 x -2 = 18
^^^ -2 is in the second multiplication slot bc 0 - 2= -2
-9 x -3 = 27
^^^ -3 is in the second multiplication slot bc 0 - 3 = -3
***Remember that when you are multiplying two negative numbers the solution will be positive
