Объяснение:

$\frac{5}{3} x + 22 = 7 \\ \frac{5}{3} x = 7 - 22 \\ \frac{5}{3} x = - 15 \\ x = - 15 \div \frac{5}{3} = - 15 \times \frac{3}{5} = - 3 \times 3 = - 9$

Answer 2

To find the values of x when the function's value is equal to 7, we can substitute 7 for y in the equation and solve for x.

Given the equation: y = (5/3)x + 22

Substituting y = 7: 7 = (5/3)x + 22

Next, we can isolate the term with x: (5/3)x = 7 - 22 (5/3)x = -15

To solve for x, we'll multiply both sides of the equation by 3/5: (3/5)(5/3)x = (3/5)(-15) x = -9

Therefore, the value of x when the function's value is equal to 7 is x = -9.
