Ответы на вопрос




3(5-x)+2(4x-3)=24
15-3x+8x-6=24
9+5x=24
5x=24-9
5x=15
x=3



To solve the equation, let's find a common denominator for the fractions and then combine them:
The equation is: (5x)/(3) + (4x-3)/(2) = 4
Step 1: Find a common denominator for the fractions, which is 6. Step 2: Convert both fractions to have a denominator of 6. Step 3: Combine the fractions and solve for x.
Step 1: Common denominator is 6. Step 2: Convert the fractions:
For the first fraction (5x/3): Multiply the numerator and denominator by 2 to get the denominator 6: (5x/3) * (2/2) = (10x/6)
For the second fraction ((4x-3)/2): Multiply the numerator and denominator by 3 to get the denominator 6: ((4x-3)/2) * (3/3) = (12x - 9)/6
Step 3: Combine the fractions:
(10x/6) + (12x - 9)/6 = 4
Now, the fractions have the same denominator, so we can add them:
(10x + 12x - 9)/6 = 4
Combine the x terms in the numerator:
(22x - 9)/6 = 4
Now, to isolate x, we can multiply both sides by 6:
6 * ((22x - 9)/6) = 6 * 4
22x - 9 = 24
Next, add 9 to both sides to isolate the x term:
22x = 24 + 9 22x = 33
Finally, divide both sides by 22 to solve for x:
x = 33/22
Simplifying the fraction (if possible):
x = 3/2
So, the solution to the equation is x = 3/2 or x = 1.5.
