if it is solution point (4, –2) must satisfy both equations
(1) –3x – 2y = –8-->-3*4-2*(-2)=-8
-12+4=-8 then-->-8=-8 ok
(2) y = 2x – 5
-2=2*4-5=3---------->-2 is not 3
the point (4, –2) is not solution of the system of equations
Answer:
y = -3x - 5

Answer:
x = 11/c
Step-by-step explanation:
To solve this equation for x, we simply need to apply equation operations and isolate the x variable.
cx - 4 = 7
cx - 4 + 4 = 7 + 4
cx = 7 + 4
cx = 11
cx * (1/c) = 11 * (1/c)
x = 11 * (1/c)
x = 11/c
