Question

945:(4у-43)= 31 решите уравнение пожалуйста

Answer 1

$945 \div (4y - 43) = 21 \\ \\ 4y - 43 = 945 \div 21 \\ \\ 4y - 43= 45 \\ y = 45+43=88$

Answer 2

945 : (4у-43)  = 31

(4у-43) = 945 : 31

(4у-43) = 30.48387

4у - 43 = 30,48387

4у = 43 + 30,48387

4у = 73,48387

у = 73,48387 : 4

у = 18,370967

Answer 3

To solve the equation, you can start by simplifying the expression on the left side by using the distributive property of multiplication over subtraction:

945:(4у-43) = 31

Rewrite as:

945 / (4у - 43) = 31

Now, cross-multiply the equation to eliminate the fraction:

945 = 31 * (4у - 43)

945 = 124y - 1343

Add 1343 to both sides:

945 + 1343 = 124у

2288 = 124у

Divide both sides by 124:

у = 2288/124

Simplify:

у = 23

Therefore, the solution to the equation is у = 23.
