To solve this equation, we need to simplify the expression first:
x + (x - 80) + (x + x - 80)/2 + 140 = 980x + x - 80 + 2x - 80)/2 + 140 = 980(4x - 240)/2 + 140 = 9802x - 120 + 140 = 9802x + 20 = 9802x = 960x = 480
So the value of x is 480.
To solve this equation, we need to simplify the expression first:
x + (x - 80) + (x + x - 80)/2 + 140 = 980
x + x - 80 + 2x - 80)/2 + 140 = 980
(4x - 240)/2 + 140 = 980
2x - 120 + 140 = 980
2x + 20 = 980
2x = 960
x = 480
So the value of x is 480.
