Question

4. X.7 = 850 - 290 5. 430 - x = 80: 16 -​

Answer 1

Ответ:

4. x = 80

5. x = 350

Пошаговое объяснение:

4.

7x = 850 - 290

7x = 560

x = $\frac{560}{7}$ = 80

5.

430 - x = 80

x = 430 - 80

x = 350

Answer 2

To solve the equations:

1. X.7 = 850 - 290

Let's simplify the equation:

X.7 = 560

To isolate X, divide both sides by 0.7:

X = 560 / 0.7

X = 800

Therefore, X is equal to 800.

2. 430 - x = 80: 16

To solve this equation, we'll simplify the right side first:

80: 16 = 5

Now we have:

430 - x = 5

To isolate x, subtract 430 from both sides:

• x = 5 - 430

• x = -425

To get the value of x, we'll multiply both sides by -1:

x = -1 * (-425)

x = 425

Therefore, x is equal to 425.
