Question

0.3(x+2)-7,6=0,4(7-x)

Answer 1

Ответ:

x=14

Пошаговое объяснение:

0,3(x+2)-7,6=0,4(7-x)

0,3x+0,6-7,6=2,8-0,4x

0,3x+0,4x=2,8-0,6+7,6

0,7x=9,8

x=14

Answer 2

To solve the equation 0.3(x+2) - 7.6 = 0.4(7-x), follow these steps:

Step 1: Distribute the terms on both sides of the equation.

0.3x + 0.3(2) - 7.6 = 0.4(7) - 0.4x

Step 2: Simplify the expressions.

0.3x + 0.6 - 7.6 = 2.8 - 0.4x

Step 3: Combine like terms.

0.3x - 7 = 2.8 - 0.4x

Step 4: Move the x terms to one side and the constants to the other side of the equation.

0.3x + 0.4x = 2.8 + 7

Step 5: Combine the x terms and the constants.

0.7x = 9.8

Step 6: Solve for x by dividing both sides by 0.7.

x = 9.8 / 0.7

x ≈ 14

So, the solution to the equation is x ≈ 14.
