Answer 1

Hey mate
.
Here is your answers
.
1. i) 4(3x + 2) - 5(6x - 1) = 2(x - 8) - 6(7x - 4)

Solution

➡12x+8-30x+5=2x-16-42x+24+4x,
➡-18x+13=-36x+8,
➡-18x+36x=8-13,18x=-5,
➡ so x=-5/18.

3(5x + 7) + 5(2x - 11) = 3(8x - 5) - 15

Solution

➡15x+21+10x-55=24x-15-15
➡25x-34=24x-30
➡25x-24x=-30+34
➡ x=4

Answer 2

1] 4(3x+2)-5(6x-1)=2(x-8)-6(7x-4)

Answer ➡

➡ 12x+8-30x+5=2x-16-42x+24

➡ 12x-30x+8+5=2x-42x-16+24

➡ 12x-30x-2x+42x=-16+24-8-5

➡ 22x= -5

➡ x = -5/22

Therefore Value Of X = -5/22 .


2] 3(5x + 7) + 5(2x - 11) = 3(8x - 5) - 15

Answer ➡

➡ 15x+21+10x-55=24x-15-15

➡ 15x+10x-24x= -15-15-21+55

➡ 1x=4

➡ x = 4

Therefore Value Of X = 4 .
