Answer:
Hi there mate!!!
let me help you
see, the answer of this question is (c)
Step-by-step explanation:
first, if we see the question, it says that which equation can't be solved in integers, that means in which equation the value of the variable is not an integer.
lets take out the answers of all the equations
1) 5y-3=-18
=5y=-18+3
=5y=-15
=y =-15/5
=y =-3
[this equation is correct as -3 is an integer]
2)3x-9=0
=3x=9
=x =9/3
=x =3
[this equation is correct as 3 is an integer]
3)3z+8=3+z
=8=3+z+3z
=8-3= z+3z
=5= 4z
=z=5/4
[this equation is not correct as 5/4 is not an integer]
4)9y+8=4y-7
=9y=4y-7+8
= 9y-4y=-7+8
= 5y = -1
= y = -1/5
=y =-5
[this equation is correct as -5 is an integer]
