Question

solve

a,4 ( m+ 3) =18
b,-2(x+3)=8​

Answer 1

${\tt{\purple{\underline{\underline{\huge{Answer:}}}}}}$

a) 4 (m + 3) = 18

4m + 12 = 18

4m = 18 - 12

4m = 6

m = 6/4

m = 3/2

b) - 2 (x + 3) = 8

- 2x - 6 = 8

- 2x = 8 + 6

- 2x = 14

x = - 14/2

x = - 7

Answer 2

a) 4(m+3)=18
=4m+12=18
=4m= 18-12=6
Therefore m=6/4=3/2
b) -2(x+3)=8
=-2x + 6=8
=-2x=8-6=2
Therefore x= 2/-2=-1
