Answer:
D. The graphs of the equations intersect each other at two places.
Step-by-step explanation:
The definition of a solution of a system of two equations in two variables is a point where the graphs intersect. A system of equations having graphs that intersect each other will have as many solutions as there are intersection points. If the graphs intersect in two places, there will be two solutions.
Let's translate the words into expressions:
11 less than 7 times a number is 
5 more than 6 times the number is 
So we have the equation

Subtract 6x from both sides:

Add 11 to both sides:

Answer:
Step-by-step explanation:quadrado de 8 + quadrado de 5 = 64 + 25 = 89
Add like terms first
-7x - 3x = -10x
so we have -10x + 2 = -8x - 8
-> 2 = 2x - 8 [added 10x to both sides]
-> 10 = 2x [added 8 to both sides]
-> x = 5 [divided both sides by 2
therefore the answer is x = 5
