Answer:

x = -23

x = -33

Step-by-step explanation:

-10(x+5) + 9x = -73

-10x - 50 + 9x = -73

x - 50 = - 73

x = -73 + 50

x = -23

-5(x + 8) + 2x = 59

-5x - 40 + 2x = 59

-3x - 40 = 59

-3x = 59 + 40

-3x = 99

x = 99/-3

x = -33

Answer:

Answer:

x=23

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

−10(x+5)+9x=−73

(−10)(x)+(−10)(5)+9x=−73(Distribute)

−10x+−50+9x=−73

(−10x+9x)+(−50)=−73(Combine Like Terms)

−x+−50=−73

−x−50=−73

Step 2: Add 50 to both sides.

−x−50+50=−73+50

−x=−23

Step 3: Divide both sides by -1.

−x/−1 = −23/−1

iragen [17]

Answer: 7 and 42.

Step-by-step explanation:

Let the two whole numbers be x and y.

From the question given, we can form an equation as:

x × y = 294 ........ i

x/y = 6 .......... ii

From equation ii

x/y = 6

x = 6y

Put the value of x back into equation i

x × y = 294

6y × y = 294

6y² = 294

y² = 294/6

y² = 49

y = ✓49

y = 7

Since x × y = 294 and y = 7,

x = 294/7

x = 42

The numbers are 7 and 42.

Algebra II Help??? Subtracting Fractions<br><br> (2x)/(y^2-x^2) - (x)/(y-x)
denis23 [38]
Make bottom number same

ok, so remember
(a-b)(a+b)=a²+b²
so

to get from (y-x) to (y²-x²), multiply 2nd fraction by (y+x)

so multiply 2nd fraction by (y+x)/(y+x)
\frac{2x}{y^2-x^2}- \frac{(y+x)(x)}{y^2-x^2}=
\frac{2x-x(x+y)}{y^2-x^2}=
\frac{2x-x^2-xy}{y^2-x^2}
