The solution is 
<em><u>Solution:</u></em>
Let us assume,
<em><u>Given system of equations are:</u></em>
<em><u>Rewrite the equation using "a" and "b"</u></em>
2a - 3b = -5 ------------ eqn 1
4a + 6b = 14 -------------- eqn 2
<em><u>Let us solve eqn 1 and eqn 2</u></em>
<em><u>Multiply eqn 1 by 2</u></em>
2(2a - 3b = -5)
4a - 6b = -10 ------------- eqn 3
<em><u>Add eqn 2 and eqn 3</u></em>
4a + 6b = 14
4a - 6b = -10
( - ) --------------------
8a = 4
Substitute a = 1/2 in eqn 1
Now let us go back to our assumed values
Substitute a = 1/2 in assumed values
Substitute b = 2 in assumed value
Thus the solution is
Answer:
27
Step-by-step explanation:
given value of Z=9
so, 3×9=27
Answer:
The total number of containers than can be filled = 
Step-by-step explanation:
The amount of blueberries Carl has = 3 1/2 cups
Now, 
⇒The amount of blueberries Carl has = 3. 5 cups
Also,the amount of blueberries each container can store = 2/3 cups
Now, 
⇒The amount of blueberries each container can store = 0.67 cups
So, \textrm{Total cpus that can be filled by blueberries} = \frac{\textrm{Toaal amount of blueberries to be stored}}{\textrm{Bluebeeries stored in 1 cup}}
= 
Now,
Hence, the total number of cups than cen be filled with the blue berries = 5 11/50
⇒ Blueberries can fill 5 full cups and 11/50th of the 6th cup.
Answer:
x=1
x=-5
Step-by-step explanation:
we know that
The solution of the system of equations is the intersection point both graphs
In this problem there are two intersection points
so
The system has two solutions
we have
one solution is the point (-4.9, 5.4) and the other (0.92, -0.42)
see the attached figure
therefore
x=1
x=-5
