Question

А)-1,4х= -4,27б)у:3,1= -6,2​

Answer 1

а)

$\displaystyle \tt -1,4x=-4,27\\\displaystyle \tt -1,4x\div(-1,4)=-4,27\div(-1,4)\\\displaystyle \tt x=3,05$

б)

$\displaystyle \tt y\div3,1=-6,2\\\displaystyle \tt y=6,2\cdot3,1\\\displaystyle \tt y=-19,22$

Answer 2

-1,4x=-4,27

-1,4x:(-1,4)=(-4,27):(-1,4)

x=3,05

y:3,1=-6,2

y:31/10=-6,2

y×10/31=-6,2

10/31y=-6,2

y=31/10×(-6,2)

y=31/10×(-31/5)

y=-961/50=19,22

Answer 3

To solve the equations, let's find the values of the variables.

a) -1.4x = -4.27

To find the value of x, divide both sides of the equation by -1.4:

x = -4.27 / -1.4

x ≈ 3.05

b) y / 3.1 = -6.2

To find the value of y, multiply both sides of the equation by 3.1:

y = -6.2 * 3.1

y = -19.22

So, the solutions for the equations are:

a) x ≈ 3.05 b) y ≈ -19.22
