Question

2,4 ( -6 x -17 ) = -7,8 ( 5 x -20 )2,4(−6x−17)=−7,8(5x−20) помогите пожалуйста дам 30 баллов

Answer 1

Пошаговое объяснение:

2,4(-6х-17)= - 7,8(5х-20)

-14,4х-40,8= - 39х+156

-14,4х+39х=156+40,8

24,6х=196,8

Х=196,8:24,6

Х=8

Answer 2

Equation Simplification

To solve the equation 2,4(−6x−17) = −7,8(5x−20), we can simplify it step by step.

Step 1: Distribute the coefficients to each term in the parentheses: 2.4 * -6x + 2.4 * -17 = -7.8 * 5x + -7.8 * -20

Step 2: Simplify each side of the equation: -14.4x - 40.8 = -39x + 156

Step 3: Combine like terms on each side of the equation: -14.4x + 39x = 156 + 40.8

Step 4: Simplify further: 24.6x = 196.8

Step 5: Solve for x by dividing both sides of the equation by 24.6: x = 196.8 / 24.6

Step 6: Calculate the value of x: x ≈ 8

Therefore, the solution to the equation is x ≈ 8.
