Question

8•(5x+1,5)=12x-(3x+7)

Answer 1

40x+12=12x-3x-7
40x-12x+3x=-7-12
31x=-19
x= -19/31

Answer 2

Let's simplify the given equation step by step:

8•(5x+1,5) = 12x - (3x+7)

First, we can simplify the left-hand side by multiplying 8 with each term inside the parentheses:

40x + 12 = 12x - (3x+7)

Next, we can simplify the expression inside the parentheses on the right-hand side by distributing the negative sign:

40x + 12 = 12x - 3x - 7

We can simplify the expression further by combining the like terms:

40x + 12 = 9x - 7

Now, we can isolate the variable on one side by subtracting 9x from both sides:

31x + 12 = -7

Finally, we can isolate the variable by subtracting 12 from both sides:

31x = -19

Therefore, the solution for the equation is:

x = -19/31
