Question

1) 5х = - 12 2) - 0,7х = - 14 3) |х|−7=0 4) 58=х6 5) х−56=43

Answer 1

Пошаговое объяснение:

1) х= -12:5

х= -2,4

2)х= -14:-0,7

х=20

3)х=0-7

х= -7

5) х= 43-(-56)

х = 99

Answer 2

It seems like you have provided a list of equations. It looks like you might want help solving these equations for the variable "x." I'll go through each equation and solve for "x":

1. $5x = -12$ Divide both sides by 5: $x = -\frac{12}{5}$

2. $-0.7x = -14$ Divide both sides by -0.7: $x = \frac{-14}{-0.7} = 20$

3. $|x| - 7 = 0$ Add 7 to both sides: $|x| = 7$

This equation has two possible solutions: $x = 7$ or $x = -7$

4. $58 = 6x$ Divide both sides by 6: $x = \frac{58}{6} = 9 \frac{2}{3}$

5. $x - 56 = 43$ Add 56 to both sides: $x = 99$

So, the solutions for each equation are:

1. $x = -\frac{12}{5}$
2. $x = 20$
3. $x = 7$ or $x = -7$
4. $x = 9 \frac{2}{3}$
5. $x = 99$
