Answer:

x is any number less than -64; i.e. -66

Step-by-step explanation:

Inequality

3x + 23y - 15 < 0

where point (x,9) satisfies this

Substitute 9 for y

3x + 23(9) - 15 < 0

3x + 207 - 15 < 0

3x + 192 < 0       Take away 192 from both sides

3x < -192             Divide both sides by 3 to isolate x

x < -64


Check:

3(-64) + 23(9) -15 < 0

-192 + 207 - 15 < 0

-192 + 192 < 0

Therefore x must be less that -64 to satisfy the point (x, 9) in this inequality.

What is 18x-(8x-7)=67
dimaraw [331]

Answer:

6

Step-by-step explanation:

18x−(8x−7)=67

Step 1: Simplify both sides of the equation.

18x−(8x−7)=67

18x+−1(8x−7)=67(Distribute the Negative Sign)

18x+−1(8x)+(−1)(−7)=67

18x+−8x+7=67

(18x+−8x)+(7)=67(Combine Like Terms)

10x+7=67

10x+7=67

Step 2: Subtract 7 from both sides.

10x+7−7=67−7

10x=60

Step 3: Divide both sides by 10.
