You use elimination the get x=5 and then plug it in to get y=0 so the coordinate is (5,0)
Find a combination calculator, but in 14 and 4, choose combinations (not permutations) and you will see the number
Divide both sides by -3
y + 5 = -15/3
Simplify 15/3 to 5
y + 5 = -5
Subtract 5 from both sides
y = -5 - 5
Simplify -5 - 5 to -10
y = -10
13x - y = 3 .....(1)
x - 6y = -33 ......(2)
eqn (2) × 13
13x - 78y = -429 .....(3)
(3) - (1)
13x - 78y = -429
13x - y = 3
(-). (+). (-)
_________________
- 77y = 431
_________________
-77y = 431
y = 431 ÷ -77
y = -5.5
Hello!
The answer is steak's temperature = chicken's temperature since they are both -6.3°C
Hope this helps!
