x= −29/4
Answer:
Step-by-step explanation:
−7(x+2)=−3(x−5)
Step 1: Simplify both sides of the equation.
−7(x+2)=−3(x−5)
(−7)(x)+(−7)(2)=(−3)(x)+(−3)(−5)(Distribute)
−7x+−14=−3x+15
−7x−14=−3x+15
Step 2: Add 3x to both sides.
−7x−14+3x=−3x+15+3x
−4x−14=15
Step 3: Add 14 to both sides.
−4x−14+14=15+14
−4x=29
Step 4: Divide both sides by -4.
−4x −4
x=29/−4
x= −29/4
Answer:
The given point A (6,13) lies on the equation. True
The given point B(21,33) lies on the equation. True
The given point C (99, 137) lies on the equation. True
Step-by-step explanation:
Here, the given equation is :
Now,check the given equation for the given points.
1) A (6,13)
Substitute x = 6 in the given equation
⇒ y= 13
Hence, the given point A (6,13) lies on the equation.
2) B (21,33)
Substitute x = 21 in the given equation
⇒ y = 33
Hence, the given point B(21,33) lies on the equation.
3) C (99, 137)
Substitute x = 99 in the given equation
⇒ y = 137
Hence, the given point C (99, 137) lies on the equation.
Not necessarily. You could have done your multiplication wrong. Or in some cases, yes, you could have to use another skill. For example, you can't solve an optimization problem with addition, you need some calculus skills under your belt.
I think it means grater or less ? Or positive or negative?
