Question

Solve the following equations:

(a) 2(m+5) = 12

(b) – 6 (x + 4) = 24

(c) 5z + 12 = -8
step by step answer ​

Answer 1

Answer:

I) 2m+10 =12

2m= 12-10 = 2

m=2/2 =1

b) -6x-24 =24

-6x = 48

x=-48/6

x= -8

c)5z =-8-12

5z= -20

z=-20/5

z=-4

Answer 2

Answer:

( a ) 2m+10=12

2m=12-10

2m=2

m=2÷2

m=1

(b) -6x-24=24

-6x=24+24

-6x=48

x=48 ÷ 6

×= 7.10
