Question

1. 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:

(1,-3)(-1,8)(6,0)(-4,8)

Step-by-step explanation:

a. x - 1 = 0

x = 1

b. x = -1

c. x = 5 + 1

x= 6

d. x = 2 - 6

x= -4

e. y = -7 +4

y = -3

f. y= 4+4

y = 8

g. y = 4-4

y = 0

h. y= -4-4

y = 8

Answer 2

(a) x - 1 = 0

=> x = 1

(b) x + 1 = 0

=> x = -1

(c) x - 1 = 5

=> x = 5-1

=> x = 4

(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
