Question

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)

Answer 1

a) $n+3=7\Rightarrow n=4$

b) $y-2=5\Rightarrow y=7$

c) $2x=8\Rightarrow x=4$

d) $2x-1=5\Rightarrow x=3$

e) $x-3=0\Rightarrow x=3$

f) $P/3=2\Rightarrow P=6$

g) $y+3=1\Rightarrow y=2$

h) $k+1=0\Rightarrow k=-1$
