There is nothing to solve y=x
Answer:
x= -2 and y=1
Step-by-step explanation:
Given equations:
-3x - 4y = 2
3x + 3y = -3
Adding these two equations, we get:
3y - 4y = -1 ⇒ <em>y=1</em>
<em> </em>⇒ 3x + 3(1) = -3 ⇒ <em>x=-2</em>

Answer:
6*132n
Step-by-step explanation:
The second part of Rita's race is about 1800 meters at a speed of 150 meters per minute.
<h3>Speed</h3>
let
- distance covered in first Part = d1
- distance covered in second Part = d2
- distance covered in third Part = d3
- speed covered in first Part = s1
- speed covered in second Part = s2
- speed covered in third Part = s3
Distance in second Part:
d₃ = 15 x 300
= 4500 m
d₂ = 2/5 × d₃
= 2/5 x 4500
d₂ = 1800 meters
Speed in second part:
S₂ = 1800 m / 12 min
S₂ = 150 meters per minute
