Solve the equation. X + 2 / 11-3 / 11 = 4 / 11 8 / 21-x + 7 / 21 = 10 / 21
x+2/11-3/11=4/11
x=4/11+3/11-2/11
x=5/11
8/21-x+7/21=10/21
x=8/21+7/21-10/21
x=5/21
Solve the equation; 2 / 3-x = 8 / 21
X=2/7
How to solve the equation of 7 / 3 × x = 21
7/3×x=21
3/7 * 7/3 * x = 21* 3/7
x = 21 * 3/7
x=9
X: 21 = 1 / 7 to solve the equation
It's the equation of ratio,
X=3
