Answer:
-6
Step-by-step explanation:
count
Let the smaller number be x and the larger number be y.
We can calculate this by using simultaneous equation, aka listing 2 equations out.
From given,
X + y = 43
Let this be equation no. 1
X + 19 = y
Let this number be equation 2.
We can do simultaneous equations either by substitute method or elimination. In this case I'm using substitute.
We can already obtain the value of y (in terms of x) in euqation no. 2, so all we gonna do is to put y into equation 1.
X + x + 19 = 43
Solve this by algebra.
2x = 43 - 19
X = 12
Now we know the exact value of x
Now substitute x = 12 into equation no. 2
12 + 19 = y
Y = 31
So the answer is 12 and 31
I think it’s the first one , sorry if i’m wrong
Answer:
The missing value is 2
Step-by-step explanation:
A direct variation satisfies the equation 
.
Since the point (-18, 12) lies on this line, it must satisfy this equation.
Hence the equation of this line is 
Now we substitute x=-3 to find y.
Therefore the missing value is 2
