Question

Solve −0.4(m+3)=4 .



m=

Answer 1

To solve the equation, distribute the -0.4 to both terms inside the parentheses, then isolate m by adding 1.2 to both sides and dividing both sides by -0.4. The solution is m = -13.

Step-by-step explanation:

To solve the equation −0.4(m+3)=4 for m, we need to isolate m. First, we can distribute the -0.4 to both terms inside the parentheses:

−0.4m - 0.4(3) = 4

−0.4m - 1.2 = 4

Next, we can add 1.2 to both sides of the equation:

−0.4m = 4 + 1.2

−0.4m = 5.2

Finally, we can solve for m by dividing both sides of the equation by -0.4:

m = 5.2 / -0.4

m = -13

Answer 2

-13

Step-by-step explanation:

−0.4(m+3)=4
=> -0.4m +(3)(-0.4) =4
=> -0.4m -1.2 =4
=> -0.4m =5.2
=> m =5.2/-0.4
=> m = -13 (answer)
