Question

5. x+3/2=-76. 9-x/7=-1​

Answer 1

Ответ:

Пошаговое объяснение:

5) х+3/2= -7

Х=-7 - 3/2

Х= - 17/2

Х= 8 целых 1/2 или -8,5

6) 9 - х/7= -1

63- х= - 7

-х= -7-63

-х= - 70

Х=70

Answer 2

To solve the equations, let's take them one at a time:

1. $x + \frac{3}{2} = -76$

First, subtract $\frac{3}{2}$ from both sides to isolate (x):

$x + \frac{3}{2} - \frac{3}{2} = -76 - \frac{3}{2}$

$x = -76 - \frac{3}{2}$

Now, calculate the right-hand side:

$x = -76 - \frac{3}{2} = -77.5$

So, the solution to the first equation is $x = -77.5$.

2. $9 - \frac{x}{7} = -1$

First, subtract 9 from both sides to isolate $-\frac{x}{7}$:

$9 - \frac{x}{7} - 9 = -1 - 9$

$-\frac{x}{7} = -10$

Now, multiply both sides by -7 to solve for (x):

$-7 \cdot \left(-\frac{x}{7}\right) = -10 \cdot (-7)$

$x = 70$

So, the solution to the second equation is $x = 70$.
