Question

1) 3/2х-1=5/3х-2 2)-3(2х-0,8)=2(х+3,6)

Answer 1

Пошаговое объяснение:

3/2x-1=5/3x-2 |6

9x-6=10x-12

9x-10x=-12+6

-x=-6

x=-6/-1=6

x=6

-3(2x-0.8)=2(x+3.6)

-6x+2.4=2x+7.2

-6x-2x=7.2-2.4

-8x=4.8

x=4.8/(-8)=-0.6

x= -0.6

Answer 2

Sure, let's solve these equations step by step.

1. $\frac{3}{2}x-1=\frac{5}{3}x-2$

First, we clear the fractions by multiplying through by 6, which is the least common multiple of 2 and 3:

$9x - 6 = 10x - 12$

Now, we isolate the variable terms on one side and the constant terms on the other:

$9x - 10x = -12 + 6$

$-x = -6$

Now, multiply both sides by -1 to solve for $x$:

$x = 6$

So, the solution for the first equation is $x = 6$.

2. $-3(2x-0.8)=2(x+3.6)$

First, simplify both sides of the equation:

$-6x + 2.4 = 2x + 7.2$

Now, isolate the variable terms on one side and the constant terms on the other:

$-6x - 2x = 7.2 - 2.4$

$-8x = 4.8$

Now, solve for $x$ by dividing both sides by -8:

$x = -0.6$

So, the solution for the second equation is $x = -0.6$.
