Question

h) 5+ 6x = 5x + 2
x+2x-1-3=x
i)
1) 13+4(2x-1)=5(x+2)
k) 4(x+5) +3(x+5)=21
1) 8(x-1)=8-4 (2x-3)

Answer 1

h) 5+6x = 5x+2

6x-5x = 2-5

6x-5x = 2-5 x=-3

i) x+2x-1-3=x

x+2x-x=1+3

x+2x-x=1+3x+x=4

x+2x-x=1+3x+x=42x=4

x+2x-x=1+3x+x=42x=4 x=4÷2

x+2x-x=1+3x+x=42x=4 x=4÷2x=2

1) 13+4(2x-1)=5(x+2)

13-8x-4= -5x-10

13-8x-4= -5x-10-8x+5x=-10-13+4

13-8x-4= -5x-10-8x+5x=-10-13+4-3x= -10-9

13-8x-4= -5x-10-8x+5x=-10-13+4-3x= -10-9-3x= -19.(-1)

13-8x-4= -5x-10-8x+5x=-10-13+4-3x= -10-9-3x= -19.(-1)x= 19/3

k) 4(x+5)+3(x+5)=21

-4x-20-3x-15=21

-4x-3x=21+20+15

-x=-56.(-1)

x=56

1) 8(x-1)=8-4(2x-3)

-8x-8=8-8x+12

-8x+8x=8-8+12

x=+12
