Решите уравнение 7.43-1.28x=1.42x+5
7.43 + -1.28x = 1.42x + 5
7.43 + -1.28x = 5 + 1.42x
7.43 + -1.28x = 5 + 1.42x
7.43 + -1.28x + -1.42x = 5 + 1.42x + -1.42x
-1.28x + -1.42x = -2.7x7.43 + -2.7x = 5 + 1.42x + -1.42x
1.42x + -1.42x = 0.007.43 + -2.7x = 5 + 0.007.43 + -2.7x = 5
7.43 + -7.43 + -2.7x = 5 + -7.43
7.43 + -7.43 = 0.000.00 + -2.7x = 5 + -7.43-2.7x = 5 + -7.43
x = 0.9
