Answer: <em>x = 19</em>
Hi! I was studying for the NYC SHSAT when this exact problem came up a year ago. I will do my best to try to answer it correctly!
Step-by-step explanation:
To start, we have to notice the similar properties of the angles. They are alternate exterior angles (?). Therefore, I think that you just have to put the angles on opposite sides of the equation!
(6x + 6) = 120
-6 -6
6x/6 = 114/6
x = 19
Left and right side are exactly same, therefore "<span>the equation is true for any value of x.</span>"
Option B
The solution of the system of equation is (-2 ,2).
<h3>What is a System of Equation ?</h3>
A system of equation is defined as the equation that have a common solution.
The system of equation is
x+y = 0
y = 2x+6
2x-y = -6
3x = -6
x = -2
y = 2
The graph of both the equations are plotted and the common point is the solution of the equations.
The solution of the system of equation is (-2 ,2).

Answer:
7 and 14
Step-by-step explanation:
Given the LCM of two numbers to be 126
If one of the numbers is 18
The other number will be 126/18 = 7
The other possible value can be gotten by multiplying the lowest prime number by 7 i.e 2×7= 14
The two possible numbers are 7 and 14
√64 = 8 (8 X 8 = 64)
3√64 = 4 (4 X 4 X 4 = 64)
