Question

-5/7-( m-1)=11/14 Решите пж

Answer 1

$-\frac{5}{7}-(m-1)=\frac{11}{14}$
$-\frac{5}{7}-m+1=\frac{11}{14}$
$-\frac{5}{7}-m+\frac{7}{7}=\frac{11}{14}$
$\frac{2}{7}-m=\frac{11}{14}$
$\frac{4}{14}-m=\frac{11}{14}$
$m=-\frac{11}{14}+\frac{4}{14}$
$m=-\frac{7}{14}=-\frac{1}{2}=-0,5$

Answer 2

To solve the equation, we need to isolate the variable "m" on one side of the equation. Let's go step by step:

Given equation: -5/7 - (m - 1) = 11/14

Step 1: Distribute the negative sign to the expression inside the parentheses. -5/7 - m + 1 = 11/14

Step 2: Combine like terms on the left side of the equation. -5/7 + 1 - m = 11/14

Step 3: Find a common denominator for -5/7 and 11/14, which is 14. Convert -5/7 to a fraction with a denominator of 14. (-5/7) * (2/2) = -10/14

So the equation becomes: -10/14 + 1 - m = 11/14

Step 4: Combine the constant terms on the left side. (1 - 10)/14 - m = 11/14

Step 5: Now, we can isolate "m" by moving the constant terms to the right side. (1 - 10)/14 = 11/14 + m

Step 6: Perform the subtraction on the left side. -9/14 = 11/14 + m

Step 7: To get "m" alone, subtract 11/14 from both sides of the equation. -9/14 - 11/14 = m

Step 8: Perform the subtraction on the left side. m = -20/14

Step 9: Simplify the fraction. m = -10/7

So, the solution to the equation is: m = -10/7
