Solve the system
y=-3x
x+y=4

x = - 2, y = 6

Step-by-step explanation:

y = - 3x

x + y = 4

Substitute y = - 3x in " x + y = 4 ",

x + y = 4

x - 3x = 4

- 2x = 4

x = 4 / - 2

x = - 2

Substitute x = - 2 in " y = - 3x ",

y = - 3x

= - 3 * ( - 2 )

y = 6

Therefore,

the value of,

x = - 2

y = 6

Hence, the system is solved.

step-by-step explanation:

in the absence of parentheses, i will have to make some assumptions:   i interpret your (3x+5/y^6)(4y^3/5)​ to mean:

3x + 5     4y^(3/5)       (3x + 5)(4)

* =

    y^6             1               y^(6-3/5)

if this is not what you expected, repost your question using parentheses to indicate whether you meant

4y^3

    or   4y^(3/5)
