Pick out the solution from the values given in the brackets against each equation :
(a) n+3=7 (10,4,0)
(b) y-2=5 (3,7,6)
(c) 2x=8 (0,3,6)
(d)2x-1=5 (6,4,3)
(e) x-3=0 (0,3,6)
(f) $\frac{p}{3} = 2$ (1,5,6)
(g) y+3=1 (4,-2,2)
(h) k+1=0 (-1,1,2)

Solution

a) $n + 3 = 7 \Rightarrow n = 4$
b) $y - 2 = 5 \Rightarrow y = 7$
c) $2 x = 8 \Rightarrow x = 4$
d) $2 x - 1 = 5 \Rightarrow x = 3$
e) $x - 3 = 0 \Rightarrow x = 3$
f) $P / 3 = 2 \Rightarrow P = 6$
g) $y + 3 = 1 \Rightarrow y = 2$
h) $k + 1 = 0 \Rightarrow k = - 1$
