Question

A) 8x - 15,3 = 6.x - 3,3;6) 18 - (6x + 5) = 4 - 7x;B) 6(x + 0,5) - 3 = 9.​

Answer 1

Ответ:

А) 8 x-6 x = - 3,3+15,3

2x=12

X = 6

Б) 18-4-5=-7x+6x

X =-9

В)

6x +3-3=9

X=9:6

x=1,5

Answer 2

It seems like you've provided a set of equations labeled as A) and B). It looks like you might want me to solve these equations for their respective variables. Let's work through them step by step.

A) $8x - 15.3 = 6x - 3.3$

Subtract $6x$ from both sides:

$8x - 6x - 15.3 = -3.3$

Simplify:

$2x - 15.3 = -3.3$

Add $15.3$ to both sides:

$2x = 11.0$

Divide by $2$:

$x = 5.5$

So, the solution for equation A) is $x = 5.5$.

B) $6(x + 0.5) - 3 = 9$

Distribute $6$ on the left side:

$6x + 3 - 3 = 9$

Simplify:

$6x = 9$

Divide by $6$:

$x = 1.5$

The solution for equation B) is $x = 1.5$.
