Give the reason for the steps used in solving the equation 3(x - 4) + 5 = 2x - 2(3 - x)

STALIN [3.7K]

$3(x - 4) + 5 = 2x - 2(3 - x) \\ 3x - 12 + 5 = 2x - 6 + 2x \\ 3x - 7 = 4x - 6 \\ 3x - 4x - 7 + 6 = 0 \\ - x - 1 = 0 \\ x = - 1$

y+7= -2/5 (x-10) What is the standard form of the equation for this line?

sveticcg [70]

The standard form of the equation of a line:

$Ax+By=C$

-----------------------------------------------------------------

$y+7=-\dfrac{2}{5}(x-10)\qquad|\text{use distributive property}\\\\y+7=-\dfrac{2}{5}x+\left(-\dfrac{2}{5}\right)(-10)\\\\y+7=-\dfrac{2}{5}x+2\cdot2\\\\y+7=-\dfrac{2}{5}x+4\qquad|\text{multiply both sides by 5}\\\\5y+35=-2x+20\qquad|\text{add 2x to both sides}\\\\2x+5y+35=20\qquad|\text{subtract 35 from both sides}\\\\2x+5y=-15$

Which equation, when solved, gives 8 for the value of X?

guajiro [1.7K]

Answer:

Option C: (5/4)x - 2 = (3/2)x - 4

Step-by-step explanation:

A) (5/2)x + (7/2) = (3/4)x + 14

Multiply through by 4 to get;

10x + 14 = 3x + 56

10x - 3x = 56 - 14

7x = 42

x = 42/7

x = 6

B) (5/4)x - 9 = (3/2)x - 12

Multiply through by 4 to get;

5x - 36 = 6x - 48

6x - 5x = 48 - 36

x = 12

C) (5/4)x - 2 = (3/2)x - 4

Multiply through by 4 to get;

5x - 8 = 6x - 16

6x - 5x = 16 - 8

x = 8

D) (5/2)x - 7 = (3/4)x + 14

Multiply through by 4 to get;

10x - 28 = 3x + 56

10x - 3x = 56 + 28

7x = 84

x = 84/7

x = 12
