Question

Answer for x with steps plz

Answer 1

5. Answer: x = -1

Explanation:

x - 9 = 8(2x + 3) - 18

x - 9 = 16x + 24 - 18 distributed 8 into 2x + 3

x - 9 = 16x + 6 simplified (added 24 and -18)

-9 = 15x + 6 subtracted x from both sides

-15 = 15x subtracted 6 from both sides

-1 = x divided 15 from both sides

7. Answer: x = 9

Explanation:

`(1)/(10)` (x + 11) = -2(8 - x)

x + 11 = -20(8 - x) multiplied both sides by 10

x + 11 = -160 + 20x distributed -20 into 8 - x

11 = -160 + 19x subtracted x from both sides

171 = 19x added 160 to both sides

9 = x divided 19 from both sides

9. Answer: x = 10

Explanation:

-8(8 - x) =
`(4)/(5)` (x + 10)

-40(8 - x) = 4(x + 10) multiplied both sides by 5

-320 + 40x = 4x + 40 distributed both left and right sides

-320 + 36x = 40 subtracted 4x from both sides

36x = 360 added 320 to both sides

x = 10 divided 36 from both sides
