What does x equal in this equation: 24+3x=3x+3(7-1) Please help this is due tomorrow!

Zinaida [17]

      24 + 3x = 3x + 3(7 - 1)

Eliminate the parentheses: 24 + 3x = 3x + 3(6)

      24 + 3x = 3x + 18

Subtract 3x from each side:    <em>24 = 18</em>

Look at that for a second. Can ANY value of 'x' make 24 equal to 18 ?
I don't think so.
There's NO number that makes the equation a true statement.

That's just another way to say: "The equation has NO solution."

Step-by-step explanation:

70+20s = 135

-70 -70

20s = 135

divide 20 both sides

s = 6.75

She can buy 6 sweaters because she cannot buy half a sweater.

s - sweaters

Solve the system of equations using multiplication. 3x – 3y = –3 5x – y = –13 What is the solution of the system?

love history [14]

ANSWER

The solution is

x=-3,y=-2

EXPLANATION

First equation

3x – 3y = –3

Second Equation:

5x – y = –13

Multiply the second equation by 3 to get:

Third equation:

15x-3y=-39

Subtract the first equation from the third equation:

$15x - 3x = - 39 - - 3$

$12x = - 36$

Divide both sides by 12,

$x = \frac{ - 36}{12} = - 3$

Put x=-3 into the first equation:

$3( - 3) - 3y = - 3$

$- 9 - 3y = - 3$

Group like terms,

$- 3y = - 3 + 9$

$- 3y = 6$

$y = - 2$

The solution is

x=-3,y=-2

Which equation represents a linear function that has a slope of 4/5<br> and a y-intercept of –6?

vredina [299]

Answer:

$\large\boxed{y=\dfrac{4}{5}x-6}$

Step-by-step explanation:

The slope-intercept form of equation of a linear function:

$y=mx+b$

m - slope

b - y-intercept

We have the slope m = 4/5 and the y-intercept b = -6. Substitute:

$y=\dfrac{4}{5}x-6$
