plzz help ​

Answer 1

Answer:

1 variable equation

Step-by-step explanation:

One variable equation is is in the form ax+b =0, where a and b are integers and has only one solution

$\frac{6(3x + 2)}{3} = \frac{(x - 1)}{7} \\ 7(18x + 12) = 3(x - 1) \\ 126x + 84 = 3x - 3 \\ 123x + 87 = 0$

Hence, one variable equation
