Question

(4,1x + 2,5) – (2,3x + 3,9) = 1,6x

Answer 1

Ответ:  x=7 .

Объяснение:

$(4,1x+2,5)-(2,3x+3,9)=1,6x\\\\4,1x+2,5-2,3x-3,9=1,6x\\\\4,1x-2,3x-1,6x=3,9-2,5\\\\0,2x=1,4\\\\x=\frac{1,4}{0,2}\; \; ,\; \; x=\frac{14}{2}\\\\\boxed {\; x=7\; }$

Answer 2

Let's solve the given equation step by step:

(4,1x + 2,5) – (2,3x + 3,9) = 1,6x

Step 1: Distribute the negative sign inside the parentheses on the left side:

4,1x + 2,5 - 2,3x - 3,9 = 1,6x

Step 2: Combine like terms on the left side:

(4,1x - 2,3x) + (2,5 - 3,9) = 1,6x

Step 3: Perform the subtraction and the addition of the coefficients:

1,8x - 1,4 = 1,6x

Step 4: Get all the x terms on one side of the equation and the constants on the other side:

1,8x - 1,6x = 1,4

Step 5: Combine like terms on the left side:

0,2x = 1,4

Step 6: Solve for x by dividing both sides by 0.2:

x = 1,4 / 0,2

Step 7: Calculate the result:

x = 7

So, the value of x that satisfies the given equation is x = 7.
