Solve for x: 2/5 (x - 2) = 4x.
A. 2/9
B. 9
C. -2/9
D. -9/2
2 answers:
(2/5)(x-2)=4x
multily both sides by 5/2 (2/5 times 5/2=10/10=1)
1(x-2)=20x/2
x-2=10x
minus x both sides
-2=9x
divide 9
-2/9=x
Step 1: Simplify both sides of the equation.
2/5(x-2)4x
Simplify: (show steps)
2/5x+-4/5=4x
Step 2: Subtract 4x form both sides.
2/5x+-4/5-4x=4x-4x
Step 3: Add 4/5 to both sides.
-18/5x+-4/5+4/5=0+4/5
Step 4: Multiply both sides by 5/-(18).
(5/-18)*(-18/5)*=(5/-18)*(4/5)
Then your answer would be -2
x= -----

Answer:
C (2,2)
B (2,-2)
A (-2,-2)
Step-by-step explanation:
3(x+1)=3x+3
-2(x-1)+6=-2x+2+6=-2x+8
3x+3=-2x+8
X=1 because 3(1)+3=6 and -2(1)+8=6
6x^2 - 7xy + 8y^2 - (x^2 - 3xy - y^2 + 2x^2 + 5xy -4y^2)
6x^2 - 7xy + 8y^2 - (3x^2 + 2xy - 5y^2)
6x^2 - 7xy + 8y^2 - 3x^2 - 2xy + 5y^2
3x^2 - 9xy +13y^2
Y+3=5(X+4)
Y+3=5x+20
Y=5x+17
