#19 how do you do the work???!

Semenov [28]

Answer:

$x=\frac{1}{3}$

Step-by-step explanation:

move the terms with $x$ to the left side of the equation:

add 3x to both sides

$3x-1+3x=1$

add 3x and 3x

$6x-1=1$

move all term not containing $x$ to the right side:

add 1 to both sides of the equation

$6x=1+1$

$6x=2$

divide each term by 6

$\frac{6x}{6}=\frac{2}{6}$

$x=\frac{2}{6}$

simplify the fraction

$x=\frac{1}{3}$

One number is 4 times a first number. A third number is 100 more than the first number. If the sum of the three numbers is 538,

larisa [96]

Answer:

292

173

Step-by-step explanation:

x = first number

4x = second number

100 + x = third number

x + 4x + 100 + x = 538

6x + 100 = 538

6x + 100 - 100 = 538 - 100

6x = 438

6x/6 = 438/6

x = 73

Check:

73 + 4(73) + 100 + 73 = 538

73 + 292 + 173 = 538

538 = 538

Troyanec [42]

Let x = total distance he covered
3x/4 by bus
1/2 . x/4 = x/8 by jogging
the remaining distance = x/8 by walking
thus x/8 = 800ft
x = 8 . 800 = 6400ft
