If x+y−z=8 and x−y+z=12, then x=

x = 10

Step-by-step explanation:

We see and show that  x = 10

This makes y = 5 and z = 7 as 5-7 (y-z) = -2

As y5-z7 = -2 then we add 10 = 8

x+y-z = 10x-2yz = 8

x-y+z =  10 -5  +7 = 12  we know  x = 10

We cna now prove.

x+y-z =8

x+5y-7z = 8

x +-2yz = 8

x = 8+2yz

x= 10

And prove

(x-5y)+7z= 12

x-y =12-7z

x = 5+5y

x=10

as x-5 (=5+7z) = 12

Have got the right answer here. Hope it helps.

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)

    5
