Question

Уровнения (3 /4 x-2/5)*3/4=3/4

Answer 1

Ответ:

(3/4х-2/5)×3/4=3/4

3/4х-2/5=3/4÷3/4

3/4х=1+2/5

3/4х=1 2/5

х=1 2/5÷3/4

х=1 13/15

------------------------

(3/4×1 13/15-2/5)×3/4=3/4

3/4=3/4

Answer 2

To solve the equation, we'll first simplify the expression within the parentheses and then solve for the variable 'x'. Here's the step-by-step process:

Given equation: (3/4)x - (2/5) * (3/4) = 3/4

Step 1: Simplify the expression within the parentheses: (3/4)x - (2/5) * (3/4) = 3/4 (3/4)x - (2/5) * (3/4) = 3/4 (3/4)x - (3/5) = 3/4

Step 2: Get rid of the fraction in front of 'x' by multiplying both sides by the reciprocal of (3/4), which is (4/3): (4/3) * [(3/4)x - (3/5)] = (4/3) * (3/4) (4/3) * (3/4)x - (4/3) * (3/5) = 1 (1)x - (4/5) = 1 x - (4/5) = 1

Step 3: Isolate 'x' on one side of the equation by adding (4/5) to both sides: x - (4/5) + (4/5) = 1 + (4/5) x = 1 + (4/5)

Step 4: Find the common denominator for 1 and (4/5), which is 5: x = (5/5) + (4/5) x = 9/5

So, the solution to the equation is x = 9/5.
