Answer:
vii. x = -1
viii. x = 9
Step-by-step explanation:
vii. 5-3x = 3-5x
=> 5x-3x=3-5
=> 2x = -2
=> x = -1
placing the value of x in the given equation,
L.H.S=> 5-3(-1) = 5+3 = 8
R.H.S=> 3-5(-1) = 3+5 = 8
L.H.S = R.H.S => Result checked
viii. x+11=5x-25
=> 5x-x = 25+11
=> 4x = 36
=> x = 9
placing the value of x in the given equation,
L.H.S => 9+11 = 20
R.H.S => 5x9 - 25= 45-25=20
L.H.S = R.H.S => Result checked
