Question

(х+3) *7=133 124:(х-14)=31

Answer 1

Ответ:

(x+3)•7=133

x+3=133:7=19

x=19-3=16

(16+3)•7=133

133=133

Ответ: x=16

124:(x-14)=31

x-14=124:31=4

x=14+4=18

124:(18-14)=31

31=31

Ответ: x=18

Answer 2

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

1. $(x + 3) \times 7 = 133$

First, distribute the 7 on the left side:

$7x + 21 = 133$

Now, subtract 21 from both sides:

$7x = 112$

Finally, divide both sides by 7:

$x = 16$

So, the solution for the first equation is $x = 16$.

2. $\frac{124}{x - 14} = 31$

Multiply both sides by $x - 14$:

$124 = 31 \times (x - 14)$

Now, divide both sides by 31:

$x - 14 = 4$

Add 14 to both sides:

$x = 18$

So, the solution for the second equation is $x = 18$.

To summarize:

• Solution for the first equation: $x = 16$
• Solution for the second equation: $x = 18$
