Question

9+10(3x-10)=2 решите уравнение

Answer 1

9+10(3x-10)=2
9+30x-100-2=0
30x=-9+100+2
30x=93
x=93/30
x=3,1
Ответ:3,1

Answer 2

9+30x-100=2
9+30x=102
30x = 102-9 = 93
x= 93/30 =3.1

Answer 3

To solve the equation 9 + 10(3x - 10) = 2, follow these steps:

Step 1: Distribute the 10 on the left side of the equation: 9 + 30x - 100 = 2

Step 2: Combine like terms on the left side: 30x - 91 = 2

Step 3: Isolate the variable term by moving the constant term to the other side of the equation: 30x = 2 + 91 30x = 93

Step 4: Solve for x by dividing both sides by 30: x = 93 / 30

Step 5: Simplify the fraction (if possible): x ≈ 3.1

So, the solution to the equation is approximately x = 3.1.
