First step: Remove the brackets by multiplying each term in the bracketds with the number infront.
(2 x x ) - (2 x 7) - 7x = 16
2x - 14 - 7x = 16
-5x = 16 + 14
-5x = 30
x = 30 ÷ -5
x = - 6

find for the value of x in the equation 2(x-7)-7x = 16
2(x-7)-7x = 16
==> 2x-14-7x = 16
==> -5x-14 = 16
==> -5x = 16+14
==> -5x = 30
==> x = -6 (divide both sides vy negative 5)

2 (x - 7) - 7x = 16
expand the brackets
2x - 14 - 7x = 16
- 5x - 14 = 16
- 5x = 30
x = -6

2 (x - 7) -7x = 16
apply distributive property to remove parentheses
2x - 14 -7x = 16
add 14 to both sides
2x - 14 - 7x + 14 = 16 + 14
2x - 7x = 30
-5x = 30
divide both sides by -5 to isolate x
-5x / -5 = 30 / -5
x = -6

2(x-7)-7x=16
2x - 14 - 7x = 16
-5x - 14 = 16
-5x - 14 + 14 = 16 + 14
-5x = 30
-5x/5 = 30/5
-x = 6
x = -6

x=-6
distribute the 2,
2x-14-7x=16
combine the x, and move 14 to the other side
-5x=30
divide by negative 5
x=-6
