Answer:
-2\9
OR
-0.2
Step-by-step explanation:
−2(4+3x)=3(x−2)
Use the distributive property to multiply −2 by 4+3x.
-
−8−6x=3(x−2)
Use the distributive property to multiply 3 by x−2.
-
−8−6x=3x−6
Subtract 3x from both sides.
−8−6x−3x=−6
-
Combine −6x and −3x to get −9x.
−8−9x=−6
Add 8 to both sides.
−9x=−6+8
-
Add −6 and 8 to get 2.
−9x=2
Divide both sides by −9.
x = 2\-9
Fraction 2\-9 can be rewritten as -2\9 by extracting the negative sign.
SO..
ANSWER IS = -2\9
Mass = density x volume

Answer:
B
Step-by-step explanation:
The given equations satisfy the given conditions. There are 2 equations and 2 unknowns, so a certain solution can be found.
This can be solved using substitution,
Substituting eqn 2 to eqn 1:
2(2y – 10) + 3y =1240
Simplifying,
y = 180
x = 350
