Question

solve: (a) 4(m+3)=18
(b) -2(x+3)=8
​

Answer 1

Answer:

$(a) 4(m + 3) = 18 \\ 4m + 12 = 18 \\ 4m = 18 - 12 \\ 4m = 6 \\ m = \frac{6}{4} \\ m = \frac{3}{2}$

$(b) - 2(x + 3) = 8 \\ - 2x - 6 = 8 \\ - 2x = 8 + 6 \\ - 2x = 14 \\ x = \frac{( - 14)}{2} \\ x = ( - 7)$

Answer 2

Answer:

(a) m= 2/3

$(b) \: x = ( - 7)$

Step-by-step explanation:

$(a) \: 4m + 12 = 18$

$4m = 18 - 12$

$4m = 6$

M= 6/4

M=2/3 ANSWER.

$\: \: (b)- 2x - 6 = 8$

$- 2x = 8 + 6$

$- 2x = 14$

$x = 14 \div ( - 2)$

$x = ( - 7)$
