To solve a problem like this, you will need to use substitution or elimination. For the sake of an example I will solve this using substitution.
First, solve one of the equations for x or y:
3x-5y=-39
3x=-39+5y
X=(-39+5y)/3
Then substitute for the value of x in the second equation:
6x+2y=-42
6((-39+5y)/3)+2y=-42
Solve for y:
-78+10y +2y=-42
-78+12y=-42
12y=36
Y=3
Once you've solved for y, you can plug in it's value to find x:
X=-39+5(3)/3
X=-24/3
X=-8
So, we can conclude that the correct answer is B. (-8,3)
Answer:
27
Step-by-step explanation:
9³÷3³=729÷27
= 27
AV = AX
2x + 1 = x + 3
x + 1 = 3
x = 2
BV = (2/3)ZV
3x + 2 = (2/3)ZV
3(2) + 2 = (2/3)ZV
6 + 2 = (2/3)ZV
8 = (2/3)ZV
24 = 2ZV
ZV = 12
