Question

1376:(34-х)=86 9680:(х+219)=16

Answer 1

34-х=1376:86
34-х=16
х=34-16
х=18

х+219=9680:16
х+219=605
х=605-219
х=386

Answer 2

To solve the equations, let's work on them one by one:

1. 1376:(34-x) = 86

To solve for x, we'll begin by cross-multiplying:

1376 * (34 - x) = 86

Next, simplify the equation:

46944 - 1376x = 86

Now, isolate the term with x:

-1376x = 86 - 46944

-1376x = -46858

To solve for x, divide both sides of the equation by -1376:

x = (-46858) / (-1376)

x ≈ 34.03 (rounded to two decimal places)

2. 9680 / (x + 219) = 16

To solve for x, we'll start by cross-multiplying:

9680 = 16 * (x + 219)

Next, simplify the equation:

9680 = 16x + 3504

Now, isolate the term with x:

16x = 9680 - 3504

16x = 6176

To solve for x, divide both sides of the equation by 16:

x = 6176 / 16

x = 386

Therefore, the solutions to the equations are:

x ≈ 34.03 and x = 386.
