Question

State whether the are linear equation or not.
a) 4x-3x/2=12
b) 2(3-x)+7=4(x+2)
c) x²=4x
d) 7x-9/2=5
e) (x+1)/2=(x+2)/3
f) 7/2x+1/3=5
please solve​

Answer 1

Answer:

no it is not linear equation

Answer 2

$a) \: 4 - x + {x}^{2} = 9$

$= > it \: is \: not \: a \: linear \: equation \: .$

$b) \: 2(3 - x) + 7 = 4(x + 2)$

$= > it \: is \: a \: linear \: equation.$

$solution \: :$

$= > 6x - 2x + 7 = 4x + 8$

$= > 4x + 7 = 4x + 8$

$= > 4x - 4x = 8 - 7$

$= > 1$

$c) {x}^{2} = 4x$

$= > it \: is \: not \: a \: linear \: equation.$

hope it helps you.
