Answer:

x = 9

Step-by-step explanation:

Step 1: Write equation

3(15 - x) = 2x

Step 2: Solve for <em>x</em>

<u>Distribute 3:</u> 45 - 3x = 2x

<u>Add 3x to both sides:</u> 45 = 5x

<u>Divide both sides by 5:</u> x = 9

Step 3: Check

<em>Plug in x to verify if it's a solution.</em>

3(15 - 9) = 2(9)

3(6) = 18

18 = 18

3(15 - x) = 2x (remove the parentheses)

45 - 3x = 2x (move the terms)

-3x - 2x = -45 (collect like terms)

-5x = -45 (divide both sides)

x = 9

A given line has the equation 10x -2.2y What is the equation, in slope-intercept form, of the line that is parallel to given lin
Andre45 [30]
10x + 2y = -2

2y = -10x - 2

y = -(10/2)x - 2/2

y = -5x  - 1    y = mx + c,   slope m = -5.

If it is parallel, then the slope of the second line ought to be -5 as well.

So you should fill -5 in the bracket.
