Question

Solve each of the following equations and check your solution:
i. 6 – y = 3 ii. m + 4 = 2m ​

Answer 1

Step-by-step explanation:

1.6-y=3

-y=3+6

-y=9

2.m+4=2m

4=2m-m

4=m

n=4

Answer 2

Answer:

(i) y = 3

(ii) m = 4

Step-by-step explanation:

(i) 6 - y = 3

Or, 6 -3 = y

Or, y = 3

Verification/Checking of solution

6 - y = 3

LHS = 6 - y = 6 - 3 = 3 = RHS

Hence, verified.

(ii) m + 4 = 2m

Or, 4 = 2m - m

Or, m = 4

Verification/Checking of solution

m + 4 = 2m

LHS = m + 4 = 4 + 4 = 8

RHS = 2m = 2(4) = 8

LHS = RHS

Hence, verified.
