Answer 1

Answer:

I hope this helps you

Step-by-step explanation:

1) 4a - 3 = -27

= 4a = -27 + 3

= 4a = -24

= a = -24/4

= a = -6

2) 2z + 3 = - 19

= 2z = -19 - 3

= 2z = -22

= z = -22/2

= z = -11

3) 7m - 1 = 20

= 7m = 20 + (-1)

= 7m = 20 - 1

= 7m = 19

= m = 19/7

4) 2.4 x - 3 = 4.2

= 2.4x = -4.2/3

= 2.4x = -1.4

= x = -1.4/2.4

= x = -7/12

5) 4m + 9.4 = 5

= 4m = 5 - 9.4

= 4m = -4.4

= m = -4.4/4

= m = -1.1

6) 6y + 4 = - 4.4

= 6y = 4.4 - 4

= 6y = 0.4

= y = 0.4/6 = 0.2/3
