Question

guys please help me with step by step explanation​

Answer 1

Answer:

m = -7

Step-by-step explanation:

Substitute x = 3-m in equation,

(3-m) - [1-(3-m)]/2 - [7(3-m)-1 + 5(3-m) = 1/2

(3-m) - [3+m]/2 - [21-m-1] + 15 - m = 1/2

(3-m) - [3+m]/2 -21 +m +1 +15 -m =1/2 {Take L.C.M for (3-m)}

(6-2m)/2 - [3+m]/2 -5 = 1/2

[6 - 2m - 3 + m]/2 - 5 = 1/2

[3 - m]/2 - 5 = 1/2 {Take L.C.M for [3-m]/2 and 5}

[3 - m -10]/2 = 1/2 {Cancel out 1/2 and 1/2}

- 7 - m = 0

m = -7
