Question

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

Answer 1

Answer:

-6

Step-by-step explanation:

7x+28+6x-18=8x-24-2x-8

13x+10=6x-32

7x=-42

x=-6

Answer 2

Answer:

x = -6

Step-by-step explanation:

expand the brackets:

7x+28 + 6x-18 = 8x-24 - 2x-8

now, collect like terms:

13x + 10 = 6x -32 (subtract 6x from both sides)

7x + 10 = -32 (minus 10 from both sides)

7x = -42 (divide by 7)

x = -6
