7x - 3y = 24
7x - 24 = 3y
(7x - 24) : 3 = y
Answer:
(-7, -10)
Step-by-step explanation:
Solve for x and y in double variable equation
y = 2x + 4
y = x - 3
y = x - 3, plug in to first equation
x - 3 = 2x + 4
x = -7
y = -7 - 3
y = -10
(-7, -10)
Answer:
no estoy segura como se debe responder
1 (x + 2y = -20) ----> x*2y= -20
-1 (x + 3y = -27) ----> x-3y= 27
(0) x + (-1) y = 7
