Good evening ,

Subtract 3x on both sides

Step-by-step explanation:

3x−5=7x+11 ⇔ (-3x)+3x−5=+(-3x)+7x+11 ⇔ −5=4x+11 ⇔ -16=4x ⇔ -4=x.

:)

Step-by-step explanation:

3x - 5 = 7x + 11

Firs step:

add 5 to both sides: 3x - 5 + 5 = 7x + 11 + 5 → 3x = 7x + 16

or

subtract 7x from both sides: 3x - 7x - 5 = 7x - 7x + 11 → -2x - 5 = 11

or

subtract 3x from both sides: 3x - 3x - 5 = 7x - 3x + 11 → -5 = 4x + 11

or

subtract 11 from both sides: 3x - 5 - 11 = 7x + 11 - 11 → 3x - 16 = 7x

If you want solution.

3x - 5 = 7x + 11       subtract 3x from both sides

3x - 3x - 5 = 7x - 3x + 11

-5 = 4x + 11         subtract 11 from both sides

-5 - 11 = 4x + 11 - 11

-16 = 4x            divide both sides by 4

-16/4 = 4x/4

-4 = x → x = -4

all it means is function 3

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
