Question
Solve the following equations by trial and error method. $7 P+6=27$
✓
Answer
Given, 7 P + 6=27 On putting P=0 in7P+6 = 27, we get (7×0)+6= 27 $\Rightarrow 0+6=27 \Rightarrow 6 \neq 27$ Now, on putting P=1 in 7P+6 = 27, we get (7×1)+6=27 $\Rightarrow 7+6=27 \Rightarrow 13 \neq 27$ Again, on putting P = 2 in 7P+6 = 27, we get (7 x 2) +6 = 27 $\Rightarrow 14 + 6=27 \Rightarrow 20 \neq 27$ Again, on putting P = 3 in 7P +6 = 27, we get (7x3) +6= 27 $\Rightarrow 21+6=27 \Rightarrow 27=27$ Hence, P = 3 is the solution of given equation 7p+6=27.
