<u>Given:</u>
The two equations are
and 
We need to solve the equations using elimination method.
<u>Elimination method:</u>
Let us multiply the equation
by 5, we get;
---------(1)
Now, multiplying the equation
by -2, we get;
--------(2)
Adding equations (1) and (2), we have;


Thus, the value of y is 3.
Substituting
in the equation
, we have;




Thus, the value of x is 4.
Hence, the solution of the system of equations is (4,3)
Therefore, Option A is the correct answer.

Step-by-step explanation:
7 years
leap years in 7 years:- 1
7 minus 1 equals to 6
6 calendar years to days:- 2190 days
so, $0.75 times 2190 = $1642.5
1642.5 plus $4.35 equals to 1646.85
Answer:
x = 9
Step-by-step explanation:
-4(6x+3)=-12(x+10)
-24x-12=-12x-120
+12 +12
-12x=-12x-108
/-12 /-12 / -12
x=9
Answer x=9
