-------> equation A
----> equation B
The <u>system</u> of <u>linear equations</u> is composed of equation A and equation B
Substitute the equation B in equation A
![y=-\frac{5}{2}[4-2y]-7](https://tex.z-dn.net/?f=y%3D-%5Cfrac%7B5%7D%7B2%7D%5B4-2y%5D-7)
Find the value of x
![x=4-2[17/4]=-4.5](https://tex.z-dn.net/?f=x%3D4-2%5B17%2F4%5D%3D-4.5)
The<u> solution</u> is the point 
Using a <u>graphing</u> tool
see the attached figure
therefore
the answer is the option A
Answer:
<h3>
Bob walked faster than Ion.</h3>
Step-by-step explanation:
90/4=22.5
Ian - 1 mile in 22.5 minutes
2x60=120
60/2=30
120+30=150
150/7=21.43
Bob - 1 mile in 21.43
Your question has been heard loud and clear.
Well -(-5)=5
5/-5/= -5
/-5/5= -5
So basically , the statement is false because -5(-5) not equal to -5/-5/
Thank you
Answer:
x = -1 and y = 1
Step-by-step explanation:
5x + 2y = -3 . . . . . . . (i)
x + 5y = 4 . . . . . . . (ii)
- Finding x in terms of y from eq. (ii) :-
x + 5y = 4
x = 4 - 5y
- Placing this value of x in eq. (i) :-
5(4 - 5y) + 2y = -3
20 - 25y + 2y = -3
-23y = - 23
<u>y = 1</u>
- Placing the value of y in eq. (i)
5x + 2(1) = -3
5x + 2 = -3
5x = - 5
<u>x = -1</u>
