-9=5+2m solve equation algebraically and verify the results
Subtract 5 from both sides, then divide both sides by 2, then insert the value for m in the equation.
ok thanks this was really helpful
You are welcome.
To solve the equation algebraically, we need to isolate the variable "m".
Starting with the equation -9 = 5 + 2m, we can begin by isolating the "2m" term by subtracting 5 from both sides of the equation:
-9 - 5 = 5 + 2m - 5
This simplifies to:
-14 = 2m
Next, to isolate the variable "m", we divide both sides of the equation by 2:
-14/2 = 2m/2
This further simplifies to:
-7 = m
Therefore, the solution to the equation is m = -7.
To verify the result, substitute the value of m back into the original equation and see if both sides are equal:
Left-hand side: -9
Right-hand side: 5 + 2(-7) = -9
Since both sides are equal to -9, the solution m = -7 is verified as correct.
