Can someone help me with this problem and show the steps:
4m-7
______ = 18
2
For the problem
(4m-7)/2 = 18
To solve for m:
The object is to get a single m on one side of the equation.
1. get rid of the denominator (2) on the left side by multiplying both sides of the equation by 2.
That gives:
4m-7 = 36
Now add 7 to both sides to get just a term with n on the left.
4m = 43
Now divide both sides by 4 to get the value of m.
m = ?
4m-7
______ = 18
2
First, multiply both sides of the equation by 2.
4m - 7 = 36
Next, add 7 to both sides of the equation.
4m - 7 + 7 = 36 + 7
4m = 42
m = 10.5
You can check it by substituting 10.5 for m in your original equation.
m= 10 3/4
thanks, now i understand
Good. I just found that I can't add. Of course 36 + 7 = 43.
Sorry
To solve the equation (4m - 7) / 2 = 18, we can follow these steps:
Step 1: Start by multiplying both sides of the equation by 2 to eliminate the denominator:
(4m - 7) / 2 * 2 = 18 * 2
This simplifies to: 4m - 7 = 36
Step 2: Next, add 7 to both sides of the equation to isolate the term with the variable:
4m - 7 + 7 = 36 + 7
This simplifies to: 4m = 43
Step 3: Now, divide both sides of the equation by 4 to solve for m:
(4m) / 4 = 43 / 4
This simplifies to: m = 43 / 4
As a decimal, m is approximately equal to 10.75.
So, the solution to the equation (4m - 7) / 2 = 18 is m = 43 / 4 or m ≈ 10.75.
