Exercise 11 Page 9

Isolate m using inverse operations.

m = 5/4

Practice makes perfect

To solve the equation, we need to isolate m using inverse operations and the Properties of the Equality.

2/7m - 1/7 = 3/14

LHS * 14=RHS* 14

2/7m * 14 - 1/7 * 14 = 3/14 * 14

MoveRightFacToNum

a/c* b = a* b/c

2 * 14/7m - 1 * 14/7 = 3 * 14/14

Multiply

28/7m - 14/7 = 42/14

Calculate quotient

4m - 2 = 3

LHS+2=RHS+2

4m - 2 + 2 = 3 + 2

Add terms

4m = 5

.LHS /4.=.RHS /4.

4m/4 = 5/4

Calculate quotient

m = 5/4
