let the ax be 3y
and xb = 4y
3y+4y= 14
7y= 14
y= 2
ax = 3y= 3*2=6
xb =4y=4*2=8
and xb = 4y
3y+4y= 14
7y= 14
y= 2
ax = 3y= 3*2=6
xb =4y=4*2=8

ax:xb = 3:4
length of line = 14 cm
3x + 4x = 14
7x = 14
x = 14 / 7
x = 2
ax = 3 * x = 3 * 2 = 6
xb = x * 4 = 2 * 4 = 8
proof : 14 = ax + xb
14 = 6 + 8
14 = 14
length of line = 14 cm
3x + 4x = 14
7x = 14
x = 14 / 7
x = 2
ax = 3 * x = 3 * 2 = 6
xb = x * 4 = 2 * 4 = 8
proof : 14 = ax + xb
14 = 6 + 8
14 = 14
