Question

(5/7х - 1/4) • 3/8 = 3/8, х =

Answer 1

Ответ:

Ответ х = одна целая три четвёртых.

Пошаговое объяснение:

5/7х-1/4=3/8:3/8

5/7х-1/4=1

5/7х=1+1/4=1 1/4

х= 1 1/4:5/7

х=7/4= 1 3/4

Answer 2

Ответ:

$(\frac{5}{7}x-\frac{1}{4}) * \frac{3}{8} =\frac{3}{8};/\frac{3}{8}\\ \frac{5}{7}x-\frac{1}{4} =1;\\ \frac{5}{7}x=\frac{5}{4};\\x=\frac{7}{4};\\x=1\frac{3}{4}.$

Answer 3

Let's solve the equation step by step:

(5/7x - 1/4) * 3/8 = 3/8

First, let's distribute the 3/8 to both terms inside the parentheses:

(3/8) * (5/7x) - (3/8) * (1/4) = 3/8

Now, simplify both sides:

(15/56)x - 3/32 = 3/8

Next, let's isolate the term with x on one side by adding 3/32 to both sides:

(15/56)x = 3/8 + 3/32

Now, find a common denominator for the fractions on the right side, which is 32:

(15/56)x = 12/32 + 3/32 (15/56)x = 15/32

To solve for x, multiply both sides by (56/15):

x = (15/32) * (56/15) x = 56/32 x = 7/4

So, the solution is x = 7/4.
