Answer:
x = -6.5
Step-by-step explanation:
solve the following linear equation by trial and error as well as by systematic method -(3x+7)=x+19
Q1 :
-(3x+7)=x+19
=> -3x - 7 = x + 19
=> -4x = 26
=> x = -26/4
=> x = -13/2
=> x = -6.5
Hit & trial Method
x = 0
=> -7 = 19
x = 1
=> -10 = 20
Difference is increasing
Let try
x = -5
=> -(-15 +7) = -5 + 19
=> 8 = 14
x = 16
=> 11 = 13
x = -7
=> 14 = 12
x would lies between -6 & -7
x = -6.5
=> 12.5 = 12.5
if 3x + 7 = x + 19
=> 2x = 12
=> x = 6
hit & trial
x = 0
=> 7 = 19
x = 1
=> 10 = 20
x = 4
=> 19 = 23
x = 5
=> 22 = 24
x = 6
=> 25 = 25
