Question

0.6(x+7)-0.5(x-3)=6.8

Answer 1

0,6x+4,2-0,5x+1,5=6,8
0,1x=6,8-5,7
0,1x=1,1
x=11
Ответ: 11

Answer 2

Let's start by simplifying the left side of the equation using the distributive property:

0.6(x+7) - 0.5(x-3) = 6.8

0.6x + 4.2 - 0.5x + 1.5 = 6.8

Now, we can combine like terms on the left side:

0.1x + 5.7 = 6.8

Next, we can isolate the variable term by subtracting 5.7 from both sides:

0.1x = 1.1

Finally, we can solve for x by dividing both sides by 0.1:

x = 11

Therefore, the solution to the equation 0.6(x+7) - 0.5(x-3) = 6.8 is x = 11.
