Question

0,6(x+7)-0,5(x-3)=6,8

Answer 1

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

Answer 2

To solve the equation, we first need to simplify it using the distributive property of multiplication and combining like terms:

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

0.6x + 4.2 - 0.5x + 1.5 = 6.8 (distribute)

0.1x + 5.7 = 6.8 (combine like terms)

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

0.1x = 1.1

Finally, we 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.
