Question

2m+0.5(m-4)=9
What is m

Answer 1

Step-by-step explanation:

Simplifying

2M + 0.5(M + -4) = 9

Reorder the terms:

2M + 0.5(-4 + M) = 9

2M + (-4 * 0.5 + M * 0.5) = 9

2M + (-2 + 0.5M) = 9

Reorder the terms:

-2 + 2M + 0.5M = 9

Combine like terms: 2M + 0.5M = 2.5M

-2 + 2.5M = 9

Solving

-2 + 2.5M = 9

Solving for variable 'M'.

Move all terms containing M to the left, all other terms to the right.

Add '2' to each side of the equation.

-2 + 2 + 2.5M = 9 + 2

Combine like terms: -2 + 2 = 0

0 + 2.5M = 9 + 2

2.5M = 9 + 2

Combine like terms: 9 + 2 = 11

2.5M = 11

Divide each side by '2.5'.

M = 4.4

Simplifying

M = 4.4
