The solution of the equations is (-2, -1)
<h3>System of equation:</h3>
2x - 3y = -1
11x - 9y = -13
Using elimination method let multiply the first equation by -3.
Therefore,
-6x + 9y = 3
11x - 9y = -13
5x = -10
x = -10 / 5
x = -2
let's find y as follows;
2(-2) - 3y = -1
-4 - 3y = -1
-3y = -1 + 4
-3y = 3
y = 3 / -3
y = -1

Answer:
C
Step-by-step explanation:
Lets begin with making this into an equation where x is the amount of months
x must be bigger than zero for them to cross
Power Plus = 34.06x + 20
Heavy Hulk = 34.31x + 32.50
When are these equal
34.06x + 20 = 34.31x + 32.50
34.06x = 34.31x + 12.50
-0.25x = 12.50
x = -50
Since x must be higher than zero(you cant go there for minus months) the answer is C
Answer:
3 unit is the correct answer
For example, if we use 5+3=8.
If you change it to 3+5, it still equals 8.
Therefore, 3+5=5+3 because at the end, they both have equal value aka both end up with 8 using the same numbers. (goes by the rule a+b=b+a)
