Answer:
x = -10
Step-by-step explanation:
Solve the equation by simplifying according to PEMDAS. Then use inverse operations to solve.
4(x+5) = 3(x-2) -2(x+2)
4x + 20 = 3x - 6 - 2x - 4
4x + 20 = x - 10
3x = -30
x = -10
D=-8
3(-8-8)-5 3(-16)-5=-48-5=-53
9(-8+2)+1=9(-6)+1=-54+1=-53
Answer:
Distributive property of equality
Step-by-step explanation:
The first thing to do in an equation is to distribute.
Answer:
≈ <em>3.4</em><em> </em>
Step-by-step explanation:
Coordinates of the point that divide segment with endpoints A( 
, 
) and B( 
, 
) in a ratio a : b are
, 
)
A(- 4, - 7)
B(8, - 4)
Ratio 8 : 5
x-coordinate is 
= 
≈ <em>3.4</em>
Answer: x = -1 and y = -2
Step-by-step explanation:
So if you know y = x-1 you can plug that in where y is in the first equation
-4x + 3(x-1) = -2
Distribute the 3:
-4x +3x -3 = -2
Combine like terms:
-x -3 = -2
Add 3 to both sides:
-x = 1
Multiply by -1:
X = -1
Then you plug that into the other equation to get y=(-1)-1
Which is -2
