Given :
Two equations :
-8x + 3y = -17 ....1)
3x - y = 7 ....2)
To Find :
The solution of the system.
Solution :
Multiplying equation 2) by 3 and adding with equation 1), we get :
(-8x + 3y) + 3(3x - y) = -17 + 21
x = 4
Putting above value of x equation 2) we get :
12 - y = 7
y = 5
Therefore, solution of system is ( 4,5 ).
Answer: y = (-11/2)x -52
Aka y=mx*b
Step-by-step explanation:
------------------------------------------------------------
Define the two numbers
-----------------------------------------------------------
Let the first number be x.
Let the second number be y.
------------------------------------------------------------
Form equations and solve x and y
------------------------------------------------------------
x + 2y = 14 ------------------ (1)
2x + y = 31 ------------------ (2)
------------------------------------------------------------
Equation (1) x 2
------------------------------------------------------------
2x + 4y = 28 ---------------(1a)
------------------------------------------------------------
Equation (1a) - 2
------------------------------------------------------------
3y = 28 - 31
3y = -3
y = -1
------------------------------------------------------------
Substitute y = -1 into (1)
------------------------------------------------------------
x + 2(-1) = 14
x -2 = 14
x = 14 + 2
x = 16
------------------------------------------------------------
Answer: x =16, y = -1
------------------------------------------------------------
The answer is 9cm^2.
Explanation: the formula for finding the area of a parallelogram is A=bh (Area=Base x Height). The base is 3cm and the height is 3cm.
