Question

a) 3(3x-1)= 2(3x+2)

b) 7(x - 2) = 5(x + 3)

c) 3(x - 2) = 4(3 - x)

me ajudem por favor​

Answer 1

a) 3(3x-1)=2(3x+2)

9x-3=6x+4

9x-6x=4+3

3x=7

x=7/3. x=2,33

b)7(x-2)=5(x+3)

7x-14=5x+15

7x-5x=15+14

2x=29

x=29/2. x=14,5

c)3(x-2)=4(3-x)

3x-6=12-4x

3x+4x=12+6

7x=18

x=18/7. x=2,57

Answer 2

a) 9x - 3 = 6x + 4
9x - 6x = 4 + 3
3x = 7
x = 7/3

b) 7x - 14 = 5x + 15
7x - 5x = 15 + 14
2x = 29
x = 29/2

c) 3x - 6 = 12 - 4x
3x + 4x = 12 + 6
8x = 18
x = 18/8
