I would go with a or b but one sec let me work it out
The solution for the given equations x + 3y = 5 and x - 3y = -1 are x=2 and y=1.
Step-by-step explanation:
The given is,
......................................(1)
....................................(2)
Step:1
By elimination method,
Subtracting Equations (1) and (2),


( - )
(
) + (
) = (
)
= 6
= 1
Step:2
Substitute the value of y in equation (1),

+ ( 3 × 1 ) = 5
= 5-3
= 2
Step:3
Check for Solution,
Substitute the values of x and y in Eqn (1),

2 + ( 3 × 1 ) = 5
5 = 5
Result:
The solution for the given equations x + 3y = 5 and x - 3y = -1 are x=2 and y=1, by elimination method.
Answer:
El propietario pagará una tasa de interés de 1472 € (736x2 años)
Step-by-step explanation:
8000 / 100 x 9.2 = 736€
736 x 2 = 1472 :)
2(5x + 15) + 2<span>(4x + 3) = 360
10x + 30 + 8x + 6 = 360
18x = 324
x = 18
so
RST = </span><span>5x + 15 = 5(18) + 15 = 105
answer
RST = 105 degree</span>
