Answer:

x= −2/7

i loveeeee mathhhhh have a great day :)

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

5(x−2)=−2(x+6)

(5)(x)+(5)(−2)=(−2)(x)+(−2)(6)(Distribute)

5x+−10=−2x+−12

5x−10=−2x−12

Step 2: Add 2x to both sides.

5x−10+2x=−2x−12+2x

7x−10=−12

Step 3: Add 10 to both sides.

7x−10+10=−12+10

7x=−2

Step 4: Divide both sides by 7.

7x/7=−2/7

x=−2/7

Mrs Lim packs 35 big and small bags of candies for her pupils. Each big bag contains 12 candies and each small bag contains 7 ca
Anastasy [175]

Answer:

there are 11 big-bags and 24 small-bags.

Step-by-step explanation:

there are x big-bags and y small-bags.

so now we can know:

(1) x + y = 35

(2) 12x + 7y = 300

in (1),we can do like this:

both left and right x7

then (x + y)x7 = 35 x 7

then 7x + 7y = 35 x 7  

then 7x + 7y = 245

now,

(1)7x + 7y =245

(2)12x + 7y = 300

we can both left and right do this: (2) - (1)

then

(12x + 7y) - (7x + 7y) = 300 -245

then

12x + 7y - 7x - 7y = 300 -245

then

12x - 7x +7y - 7y =300 -245

then

5x =55

then

5x ÷ 5 = 55 ÷ 5

then

x = 11

because

x + y =35;x=11

so

11 + y =35

11+ y -11 = 35 -11

then

y = 24

now we know:there are 11 big-bags and 24 small-bags.
