Question

h) 7(x-2) = 5(x+3)
i) 3(2x-1) = -2(x+3)
j) 5x-3(x+2) = 15
k) 2x+3x+9 = 8(6-x)
1) 4(x+10)-2(x-5) = 0
m) 3(2x+3)-4(x-1) = 3
n) 7(x-1)-2(x-5)=r-5

Answer 1

Resposta:

h)7x-14=5x+15.

7x-5x=15+14

2x =29

x=29/2

x=14,5

I)6x-3=-2x-6

6x+2x=-6+3

8x. =-3

x=-3/8

j)5x-3x-6=15

5x-3x=15+6

2x=21

x=21/2

x=10,5

k)2x+3x+9=48-8x

2x+3x+8x=48-9

13x=39

x=39÷13

x=3
