M/2 - 5 + 3 = 2
Put each term in m/2 - 5 + 3 over the common denominator 2: m/2 - 5 + 3 = m/2 - 10/2 + 6/2:
m/2 - 10/2 + 6/2 = 2
m/2 - 10/2 + 6/2 = (m - 10 + 6) / 2:
(m - 10 + 6) / 2 = 2
Subtract like terms. 6 - 10 = - 4:
(m - 4) / 2 = 2
Multiply both sides of (m - 4) / 2 = 2 by 2:
(2 (m - 4)) / 2 = 2*2
(2 (m - 4)) / 2 = 2/2 * (m - 4) = m - 4:
m - 4 = 2*2
2*2 = 4:
m - 4 = 4
Add 4 to both sides:
m + (4 - 4) = 4 + 4
4 - 4 = 0:
m = 4 + 4
4 + 4 = 8:
Answer: m = 8
