Step-by-step explanation:
im just gonna go through this 1 at a time. starting at 1.
12 + (14x9) = 138
(12x5)+(14x5) = 130
(12x4)+(14x6) = 132
(12x8)+(14x2) = 124
(12x6)+(14x4) = 128
Step-by-step explanation:
7x-2 ) + (١١x -34)
so u will get the answer
after getting it u can easy get y
The simultaneous equations are
2x - 7y = 4 (1)
3x + y = -17 (2)
Write (2) as
y = - 3x - 17 (3)
Substitute (3) into (1).
2x - 7(-3x - 17) = 4
2x + 21x + 119 = 4
23x = -115
x = -5
This is the equation obtained after substituting y from the second equation into the first equation.
The solution for y is
y = -3(-5) - 17 = -2
Answer: x = -5
Note: The solution is x = -5, y = -2.
