2m +7=9

2m=9-7

2m=2

m=2

there is answer is 2 hope u get it

Answer 2

Given:

The equation -

• 2m + 7 = 9

What To Find:

We have to find -

• The value of m.

How To Find:

To find, we have to -

• Simplify the equation from both sides.
• Take variables to any one side and numbers to another side.
• Solve the equation.
• Find the value.

Solution:

⇒ 2m + 7 = 9

Take 7 to RHS,

⇒ 2m = 9 - 7

Subtract 7 from 9,

⇒ 2m = 2

Take 2 to RHS from LHS,

⇒ m = 2 ÷ 2

Divide 2 by 2,

⇒ m = 1

Verification:

⇒ 2m + 7 = 9

Substitute the value of m,

⇒ 2 × 1 + 7 = 9

Multiply 2 with 1,

⇒ 2 + 7 = 9

Add 2 and 7,

⇒ 9 = 9

∵ LHS = RHS

∴ Hence, verified.

Final Answer:

∴ Thus, the value of m is 1.
