Question

Which of these following set of linear equations are equivalent?
x+2=9 and x+5=6
x+2=8 and 11+x=17
x+9=-15 and x-6=-30
x+16=17 and x-2=9​

Answer 1

Step-by-step explanation:

x+2=9

x=7

and x+5=6

x=1

x+2=9 and x+5=6 are not equivalent

x+2=8

x=6and

11+x=17

x=6

x+2=8 and 11+x=17 are equivalent

x+9=-15

x= -24

and x-6=-30

x= -24

x+9=-15 and x-6=-30are equivalent

x+16=17

x=1

and x-2=9

x=11

x+16=17 and x-2=9 are not equivalent
