Given:
The system of equation:
-------- (1)
--------- (2)
To find the values of x and y.
We will use substitution method.
From (1) we get,

We will put the value of y in (1) and we get,

or, 
Now we will apply middle term factor method.




so, x = 4 and 1
Now,
Substitute x = 4 in (1) we get,

And putting x = 1 in (1) we get,

Hence, the solution of the given system of equation is (4,-8) and (1,-5)
Thus, Option A is the correct answer.
<span>The answer is that x = 21/9.
Start with the original: 4(2x - 1) - 7 = 4 - x + 6
Now distribute the 4:</span> <span> 8x - 4 - 7 = 4 - x + 6.
Now combine the like terms. 8x - 11 = -x + 10.
Now add x to both sides. 9x - 11 = 10.
Now add 11 to both sides. 9x = 21.
And divide by 9 on both side. x = 21/9. </span>
Answer:
106.25
Step-by-step explanation:
99.5+113= 212.5 /2 = 106.25
Answer: 15 x (1/3)
Step-by-step explanation: 15 divided by 3 is 15 right. When you multiple 15 and 1/3 it is like taking one third out of 15. One third out of 15 is 5. Hope this helped! :P
Answer:
1/3
Step-by-step explanation:
6+4+5=15 total number of balls
blue = 5 balls
5/total number = 5/15
=1/3
