Question

X+0,42x+2/3×0,42x=340

Answer 1

Х+0,42х+2/3*0,42x=340
1,42х+0,28х=340
1,7х=340
х=340:1,7
х=200

Answer 2

To solve this equation, we need to simplify the left-hand side first:

x + 0.42x + (2/3)×0.42x = x + 0.42x + 0.28x = 1.7x

Now we can substitute this expression back into the original equation:

1.7x = 340

To solve for x, we can divide both sides by 1.7:

x = 200

Therefore, the solution to the equation is x = 200.
