Answer:

x = -10

x = 7

Step-by-step explanation:

2(x+3) = x - 4

2x + 6 = x - 4

2x -x = - 4 - 6

x = - 10

4(5x-2) = 2(9x+3)

20x - 8 = 18x +6

20x - 18x = 6 + 8

2x = 14

x = 7

have a nice day :D

2x(x + 3)= x - 4
2x + 6 = x - 4
2x - x - 4
X = -10

4(5x + -2) = 2(9x + 3)
20x - 8 = 18x + 6
20x -18x = 6 + 8
2x/2 = 14\2
X = 7
