Answer:
(If solving for x) X = 2y-1
Step-by-step explanation:
Y-2 = 1/2(x-3)
Distributive property
Y-2 = 1/2x - 1.5
Addition property of equality
Y-0.5=1/2x
Multiplication property
2Y-1=X
Symmetric property
X = 2y-1
The answer would be 42
42*3 = 126
126+5 = 131
3(n)+5=131
3(n)+5 -5= 131-5
3(n)=126
3(n)/3= 126/3
n= 42
Answer:
The answer is
and 
Step-by-step explanation:
Given:
-4x-2y=14
-10x+7y=-24
Now, to solve it by elimination:
......(1)
......(2)
So, we multiply the equation (1) by 7 we get:

And, we multiply the equation (2) by 2 we get:

Now, adding both the new equations:




<em>Dividing both the sides by -8 we get:</em>

Now, putting the value of
in equation (1):




<em>Subtracting both sides by 25 we get:</em>

<em>Dividing both sides by -2 we get:</em>

Therefore, the answer is
and
