Answer:
x= 1/3
y = -8
Step-by-step explanation:
-2y+ y = 8 equation 1
-3x -y =7 equation 2
using equation 1 we have:
-2y+ y = 8
-y = 8
y = -8 equation 3
using equation 3 in equation 2 we have:
-3x -y=7
-3x -(-8)=7
-3x +8 =7
-3x = 7-8
-3x = -1
x= 1/3

Answer:
P22039
Step-by-step explanation:
Cost of new television = 29078
Let the price of old model television = x
2x - 15000 = 29078
2x = 29078 + 15000
2x = 44078
2x/2 = 44078 /2
x = 22039
Hence, price of old model television is P22039
<h2><u>Given</u> :-</h2>
x^2 - x - 6
<h2><u>Solution</u> :-</h2>
Factorisation :-
x^2 - x - 6
= (x - 3)(x + 2)
