Question

(3,1х+3,1)-(1,8х+1,8)=1,6х+1,6​

Answer 1

Ответ:

3,1x+3,1-1,8x-1,8=1,6x +1,6

1,3x +1,3=1,6x +1,6

-0,3x=0,3

X=-1

Answer 2

It seems like you're trying to perform a subtraction operation on two expressions:

(3.1x + 3.1) - (1.8x + 1.8)

To simplify this expression, you can distribute the negative sign (minus sign) to each term within the parentheses on the right side of the subtraction:

(3.1x + 3.1) - 1.8x - 1.8

Now, you can combine like terms by adding or subtracting the coefficients of the 'x' terms and the constants separately:

(3.1x - 1.8x) + (3.1 - 1.8)

Now, simplify the expression:

1.3x + 1.3

So, the simplified form of the expression (3.1x + 3.1) - (1.8x + 1.8) is 1.3x + 1.3.
