Question

EXERCISE 4.2
(a) x-1=0
(e) y - 4=-7
(b) x + 1 = 0
(f) y - 4=4
(C) x-1= 5 (d) x + 6 = 2
(g) y + 4 = 4 (h) + 4 =- 4
hle and then solve the equation:
Give first the
1. Give first the step you will use to separate the variable and then solve the equation:​

Answer 1

Step-by-step explanation:

a) x-1=0

=0+1

=1

b) x+1=0

=0-1

= -1

c) x-1=5

=5+1

=6

d) x+6=2

=2-6

= -4

e) y-4= -7

= -7-4

= -11

f) y-4=4

=4+4

=8

g) y+4=4

=4-4

=0
