Question

5(10 – 4х) = 50 і -3(2 – х) = -9.

Answer 1

50-20х=50
-20х=50-50 (числа с неизвестными влево, обычные направо, и меняем при этом знаки)
-20х=0
х=0
(Не уверенна)
-6+3х=-9
3х=-9+6
3х=-3
х=-1
Надеюсь вас так учили

Answer 2

To solve the system of equations:

1. 5(10 - 4x) = 50
2. -3(2 - x) = -9

First, simplify each equation:

1. 5(10 - 4x) = 50 Distribute 5 on the left side: 50 - 20x = 50

2. -3(2 - x) = -9 Distribute -3 on the left side: 6 - (-3x) = -9

Now, continue to solve for x in each equation:

1. 50 - 20x = 50 Subtract 50 from both sides: -20x = 0

2. 6 - (-3x) = -9 Add 6 to both sides: -3x = -9 + 6 -3x = -3

Now, solve for x in each equation:

1. -20x = 0 Divide both sides by -20: x = 0

2. -3x = -3 Divide both sides by -3: x = 1

So, the solution to the system of equations is x = 0 and x = 1.
