Answer 2

0,4(6x-7)=0,5 (3x+7)

7(1,4+1,8)-27,6=10,1y

3(5-x)+13=4(3x-8)

Answer 3

To solve the equation, we need to find the value of "x" that satisfies the equation:

0.4(6x - 7) = 0.5(3x + 7)

Let's simplify the equation step by step:

Step 1: Distribute the coefficients on each side of the equation:

2.4x - 2.8 = 1.5x + 3.5

Step 2: Move the variable terms (with "x") to one side of the equation and the constant terms to the other side:

2.4x - 1.5x = 3.5 + 2.8

Step 3: Combine the "x" terms and the constants:

0.9x = 6.3

Step 4: Now, isolate "x" by dividing both sides by 0.9:

x = 6.3 / 0.9

Step 5: Finally, calculate the value of "x":

x = 7

So, the solution to the equation is x = 7.
