Question

A)2x=8б)3x=-15в)-4x=-1г)3x+27=0​

Answer 1

Ответ:

2x=8

Разделим обе части уравнения на 2:

a) x=4

3х=-15

Также разделим обе части уравнения на 3:

b) x=-5

-4х=-1

Точно также делим обе части уравнения на -4:

c) х= 1/4

Можно записать дробь в виде:

х=0.25

3х+27=0

Перенесём 27 в правую сторону, при этом, поменяем знак на отрицательный.

d) 3x=-27

x=-9

Answer 2

It seems like you have provided a list of equations. If you would like me to solve these equations for the variable "x," I can certainly help with that. Here are the solutions for each equation:

A) 2x = 8: To solve for x, divide both sides of the equation by 2: 2x / 2 = 8 / 2 x = 4

B) 3x = -15: To solve for x, divide both sides of the equation by 3: 3x / 3 = -15 / 3 x = -5

C) -4x = -1: To solve for x, divide both sides of the equation by -4: (-4x) / (-4) = (-1) / (-4) x = 1/4

D) 3x + 27 = 0: To solve for x, first subtract 27 from both sides of the equation: 3x + 27 - 27 = 0 - 27 3x = -27

Now, divide both sides by 3 to isolate x: (3x) / 3 = (-27) / 3 x = -9

So, the solutions for each equation are: A) x = 4 B) x = -5 C) x = 1/4 D) x = -9
