Question

Give first the step you will use to separate the variable and then solve the equation:
(a) x – 1 = 0 (b) x + 1 = 0
(c) x-1 = 5 (d) x + 6 = 2
(e) y - 4 =-7 (f) y - 4 = 4
(g) y + 4 = 4
(h) y+ 4 = – 4
​

Answer 1

Answer:

a. x-1=0

x=0+1

X=1

B.x+1=0

X=0-1

X=-1

C.x-1=5

X=5+1=6

X=6

D.x+6=2

X=2-6

X=-4

E.y-4=-7

Y=-7+4

Y=-3

F.y-4=4

Y=4+4

Y=8

G.y+4=4

Y=4-4

Y=0

H.y+4=-4

Y=-4-4

Y=-8
