Question

Решы уравнение 87:(4x+5)=3

Answer 1

87:(4x+5)=3

4x + 5 = 87 : 3

4x + 5 = 29

4x = 29 - 5

4x = 24

x = 24 : 4

x = 6

Answer 2

To solve the equation $\frac{87}{4x+5} = 3$, follow these steps:

Step 1: Eliminate the fraction by multiplying both sides of the equation by $4x+5$:

$(4x+5) \times \frac{87}{4x+5} = 3 \times (4x+5)$

Step 2: Simplify:

$87 = 3(4x+5)$

Step 3: Distribute 3 on the right side:

$87 = 12x + 15$

Step 4: Isolate the variable term (12x) on one side of the equation by subtracting 15 from both sides:

$87 - 15 = 12x$

$72 = 12x$

Step 5: Finally, solve for x by dividing both sides by 12:

$x = \frac{72}{12}$

$x = 6$

So the solution to the equation is $x = 6$.
