<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.
Answer:
b = -ax + 4x + 2
Step-by-step explanation:
8x - 3x + 2 - x = ax + b
~Combine like terms
4x + 2 = ax + b
~Subtract ax to both sides
4x - ax + 2 = b
~Rewrite
b = -ax + 4x + 2
Best of Luck!
Answer:
-12
Step-by-step explanation:
r = -3
4/9 * (-3) = -4/3
-4/3 * (-3) = 4
so, 4 * (-3) = -12
