30 is the value of x given of above quertion
Answer:
x = - 1
Step-by-step explanation:
Given
3x + 2 = y and y = - 1
Substitute y = - 1 into the equation and solve for x, that is
3x + 2 = - 1 ( subtract 2 from both sides )
3x = - 3 ( divide both sides by 3 )
x = - 1
This is verified by the point on the graph with coordinates (- 1, - 1)
Answer:
the answer is 4!!!!!!!!!!!!!!
Answer:
22, -6
Step-by-step explanation:
Create a system of equations.
x= the larger number
y=the smaller number
Using what you know, create the equations:
x+y=16
3x-y=72
Now add the two equations together. (elimination method)
x+y=16
+ 3x-y=72 (the y's cancel out)
-----------------
4x = 88 Divide.
x = 22
Now plug in x=22 into one of your equations to solve for y.
x+y=16
22+y=16
y=-6
The numbers are 22 and -6.
