How to solve the equation 7x-36 = 27

How to solve the equation 7x-36 = 27

7x-36=27
7x=27+36
7x=63
x=9

X-0.7x = 3.6 to solve the equation

X-0.7=3.6
(1-0.7)x=3.6
0.3x=3.6
x=12

First, 4x + 9.6x = 68 & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; ② 7x-4 × 0.73 = 25.08

（1）4x+9.6x=68          13.6x=68     13.6x÷13.6=68÷13.6              x=5（2）7x-4×0.73=25.08        7x-2.92=25.08   7x-2.92+2.92=25.08+2.92              7x=28                  x=4
