To get system B, the second equation in system A was replaced by the sum of that equation and the first equation multiplied by 5. The solution to system B will be the same as the solution to system A.
<h3>How to find the relationship between two equations?</h3>
System A equations:
-x - 2y = 7 ------ (1)
5x - 6y = -3 ------(2)
We multiply the first equation by 5, to get :
-5x - 10y = 35 -----(3)
The sum of equation (2) and equation (3) gives:
-16y = 32
y = 32/-16
y = -2
Thus, solution of system B is;
-x - 2(-2) = 7
-x + 4 = 7
x = -3
So, the solution of system B is (-3, -2), that means the solution of both systems are same.

Answer:
b<-7 or b>-1
Step-by-step explanation:
explanation: -6b>42 turns into -42>6b then divide by 6 on both sides and you get -7>b
for the other inequality, you take 4b+6>2 and then subtract6 from both sides, from there you will get 4b>-4 and that will be b>-1
Answer:
3. 3 and 4
4. √9+√2, 8/3, √5 - 5, -π
Step-by-step explanation:
3. √46/2 is 3.39... which is between 3 and 4
4. √9+√2=4.4..
8/3=2.6...
√5-5= -2.7..
-π= -3.14..
(hope this helps :P)
