12:(8x+4)=4:(10x-6) пропорцию использовать

Answer 1

$\frac{12}{8x + 4} = \frac{4}{10x - 6} \\ 12 \times (10x - 6) = 4 \times (8x + 4) \\ 120x - 72 = 32x + 16 \\ 120x - 32x = 16 + 72 \\ 88x = 88 \\ x = 1$

Answer 2

To solve the proportion 12:(8x+4) = 4:(10x-6), we can cross-multiply and then solve for x. Here's the step-by-step solution:

Step 1: Cross-multiply the proportion: 12 * (10x-6) = 4 * (8x+4)

Step 2: Distribute on both sides: 120x - 72 = 32x + 16

Step 3: Get all the x terms on one side and constants on the other side: 120x - 32x = 16 + 72 88x = 88

Step 4: Solve for x: x = 88/88 x = 1

So, the value of x that satisfies the given proportion is x = 1.
