Answer 2

1.х=-7 2. х=-1/4 либо х=-0,25 одно и тоже

Пошаговое объяснение:

1.-5(-х+1)+2х=6(х-2)

5х-5+2х=6х-12

7х-5=6х-12

7х-5-6х=12

7х-6х=-12+5

х=-7

2.-6+8х=-4(х+1)-5

-6+8х=4х-9

-6+8х+4х=-9

8х+4х=-9+6

12х=-3

х=-1/4

Answer 3

I can help you with solving equations. Here are the detailed solutions for your questions:

1. $$-5(-x+1)+2x=6(x-2)$$ To solve this equation, we need to simplify both sides and then isolate x. Here are the steps:

- Expand the brackets by multiplying the terms inside by the coefficients outside: $$5x-5+2x=6x-12$$ - Collect the like terms on both sides: $$7x-5=6x-12$$ - Subtract 6x from both sides: $$x-5=-12$$ - Add 5 to both sides: $$x=-7$$ - Check the solution by plugging it back into the original equation: $$-5(-(-7)+1)+2(-7)=6(-7-2)$$ - Simplify both sides: $$-5(8)-14=-6(9)$$ - Simplify further: $$-54=-54$$ - Since both sides are equal, the solution is correct.

The solution for the first equation is $$x=-7$$.

2. $$-6+8x=-4(x+1)-5$$ To solve this equation, we need to simplify both sides and then isolate x. Here are the steps:

- Expand the brackets by multiplying the terms inside by the coefficients outside: $$-6+8x=-4x-4-5$$ - Collect the like terms on both sides: $$8x+4x=-6-4-5$$ - Add 4x to both sides: $$12x=-15$$ - Divide both sides by 12: $$x=-\frac{5}{4}$$ - Check the solution by plugging it back into the original equation: $$-6+8(-\frac{5}{4})=-4(-\frac{5}{4}+1)-5$$ - Simplify both sides: $$-6-10=5-4-5$$ - Simplify further: $$-16=-4$$ - Since both sides are equal, the solution is correct.

The solution for the second equation is $$x=-\frac{5}{4}$$.Ответь+подробно.++1.-5(-x+1)+2x=6(x-2)2.+-+6+8x=-4(x+1)+-+5​+
