b.3-2(2-y)=7
with the working please help me
​

Answer 1

Step-by-step explanation:

a 18 divide by 4 then it's ans. added by 3

Answer 2

Answer:

a)

$4(m + 3) = 18$

$m + 3 = \frac{18}{4}$

$m + 3 = 4.5$

$m = 4.5 - 3 \\ \: \: \: \: \: = 1.5 \\ \\ therefore \: m \: = 1.5$

b)

$(3 - 2)(2 - y) = 7$

$(1)(2 - y) = 7$

$2 - y = 7 \\ - y = 7 - 2 \\ - (y) = 5 \\ y = - 5$
