Who can help me solve the equation 9x-0.9 = 3.66.5 * 1.8 + x = 20.58x + x23.47x + 6x = 29.9

9x-0.9=3.6
9x=3.6 0.9
x=0.5
6.5*1.8 x=20.5
x=20.5-6.5×1.8
x=8.8
7x 6x=29.9
13x=29.9
x=2.3
The landlord doesn't understand 8x x 23.4. Is it 8x x = 23.4 if it is
8x x=23.4
9x=23.4
x=2.6
Ha ha! Thank you!

1.8x + 0.6x = 9.6

1.8x+0.6x＝9.6
2.4x=9.6
x=9.6÷2.4
x=4
