Question

(60-x)+ x +(70-x)= 100. Find x​

Answer 1

Answer:

x= 30

Step-by-step explanation:

60- x + x + 70 - x = 100

130 - x = 100

-x = 100-130

-x = -30

Thus, x= 30

Answer 2

solution:

$(60-x)+ x +(70-x)= 100$

$60 - 2x + (70 - x) = 100$

$- 2x + (70 - x) = 100 - 60$

$- 2x + (70 - x) = 40$

$</u><u>-1x</u><u>=</u><u>4</u><u>0</u><u>-</u><u>7</u><u>0</u><u>$

$</u><u>-1x</u><u>=</u><u>(</u><u>-</u><u>3</u><u>0</u><u>)</u><u>$

$</u><u>x</u><u>=</u><u>3</u><u>0</u><u>$
