Solve the following equations by trial and error method:
$(i).\ 5p+2=17$
$(ii).\ 3m-14=4$
Given:
Given equations are
(i) $5p+2=17$
(ii) $3m-14=4$
To do:
We have to solve the given equations by trial and error method.
Solution:
(i) $5p+2=17$
$5p+2=$L.H.S
By putting, $p=0$,
$5(0)+2=2$
$≠17$
By putting, $p=1$,
$5(1)+2=7$
$≠17$
By putting, $p=2$,
$5(2)+2=12$
$≠$R.H.S
By putting, $p=3$,
$5(3)+2=17$
$=$R.H.S
Therefore, $p=3$ is a solution of the equation.
(ii) $3m-14=4$
$3m-14=$L.H.S
By putting, $m=5$,
$3(5)-14=1$
$≠6$
By putting, $m=6$,
$3(6)-14=4=$R.H.S.
Therefore, $m=6$ is a solution of the equation.
