Answer: x = 5, y = 8 Step-by-step explanation: Another way to write (x+y, 2x-y)= (13, 2) is x + y = 13 — (1) 2x – y = 2 — (2) using the elimilation method, Rewriting (1), y = 13 – x –(1)’ Replacing (1)’ into (2), 2x – ( 13 – x) = 2 2x – 13 + x = 2 3x = 15 x = 5 — (3) Replacing (3) into (1), 5 + y = 13 y = 8 — (4) Accorindg to (3) and (4), x = 5, y = 8 If this helps you, please give brainliest!

Answer:
Step-by-step explanation:
comparing corresponding elements
x + y = 13
2x – y = 2
Now use substitution method.
x + y = 13
x = 13 – y equation(i)
substitute the value of x
2x – y = 2
2(13 – y) – y = 2
26 – 2y – y = 2
-3y = 2 – 26
y = -24/-3
y = 8
substitute the value of y in eqaution(i)
x = 13 – y
x = 13 – 8
x = 5
therefore , x = 5 and y = 8
To check :
x + y = 13
when we add x and y then must come 13
5 + 8 = 13
13 = 13
2x – y = 13
substitute the value of x and y . REsult must come 2
2*5 – 8 = 2
10 – 8 = 2
2 = 2
10 – 8 = 2
Answer:
x = 5, y = 8
Step-by-step explanation:
Another way to write (x+y, 2x-y)= (13, 2) is
x + y = 13 — (1)
2x – y = 2 — (2)
using the elimilation method,
Rewriting (1), y = 13 – x –(1)’
Replacing (1)’ into (2),
2x – ( 13 – x) = 2
2x – 13 + x = 2
3x = 15
x = 5 — (3)
Replacing (3) into (1),
5 + y = 13
y = 8 — (4)
Accorindg to (3) and (4),
x = 5, y = 8
