Answer:
The missing number is 4
Step-by-step explanation:
Given
21 x 39 x _____ x 19 divided by 12 = 5187
Required
Fill in the gap
Let the missing number be represented with y; So, the expression becomes

Multiply both sides by 12


Rearrange the expression on the left hand side


Divide both sides by 15561



Hence, the missing number is 4
Answer:
x = -2 and y = 0
Step-by-step explanation:
5x + y = -10
4x - 7y = -8
Rearrange the first equation to equal y.
5x + y = -10
y = -10 - 5x
Replace y in the second equation with the first equation.
4x - 7y = -8
4x - 7(-10 - 5x) = -8
4x - (-70 -35x) = -8
4x + 70 + 35x = -8
Rearrange the equation to find x.
4x + 35x = -8 - 70
39x = -78
x = -2
Now that you know x, use the rearranged first equation to find y.
y = -10 - 5x
y = -10 - 5(-2)
y = -10 + 10
y = 0
