Question

cuál de las siguientes expresiones representa una ecuación lineal.
a)xy+5=5
b) x + 1 = 8
c) x2+5x+6=0
d) x + 5xy = 3y​

Answer 1

Explicación paso a paso:

a) xy + 5 = 5

xy = 5 - 5

ans = 0

so - oo + 5 =5.

b) x + 1 = 8

x = 8 - 1 .

ans = x = 7

so ans is 7 + 1 = 8

c) x2 + 5× + 6 = 0

x = 0

x = 0

ans = 02 + 50 + 6 =0

hor l am explam so let s start

so 02 + 50

answer is 52 + 6

ans= 58

so you think that answer is 0 that your question is not correct so rewrite the question then l can explain.

d) x + 5xy = 3y

x = 15

x + y

10

then subtract it 10 + 5

ans = 15

y = 0

15 + 15 = 30

l hope that my answer is helpful for you.
