Question

15+15m=0 what is the value of m?

the value of m is -3 that I know I want method.
pls it's urgent​

Answer 1

What is the value of m!?

Given equation: 15 + 15m = 0

Some rules to remember:

• + = -
• - = +
• × = ÷
• ÷ = ×

Explanation: Firstly let us know that which number is in right side of equality sign and which is at left. At right side the number 0 is present and at left side 15 + 15m is present. Now let's carry on,

Let 15m be constant at its place and let us move 15 at right side of equality sign with opposite sign. Now let us subtract. Now as in 15m, 15 is multiplied with m here so let us take 15 at the right side of equality sign with opposite side of its own and let m be constant there. Afterthat let's divide and we get our final result!

Required solution:

→ 15 + 15m = 0

→ 15m = 0 - 15

→ 15m = -15

→ m = -15/15

→ m = -1

Verification:

Some rules to remember:

• - × - = +
• + × + = +
• + × - = -
• - × + = -

Explanation: Let us verify our result that our answer that is -1 is correct or not! We have to write the equation as it is. And have to put -1 at the place of m wisely and further have to solve. If LHS = RHS then our answer will be verified and it is absolutely correct!

→ 15 + 15m = 0

→ 15 + 15(-1) = 0

→ 15 + (-15) = 0

→ 15 - 15 = 0

→ 0 = 0

→ LHS = RHS

• Henceforth, verified!!!
