Answer:

\boxed{x = 10}

Step-by-step explanation:

=  > 2x + 12 =  - 2(4 - 2x) \\  \\  =  > 2x + 12 =  (( - 2) \times 4) - (( - 2) \times 2x) \\  \\  =  > 2x + 12 =  - 8 - ( - 4x) \\  \\  =  > 2x + 12 =  - 8 + 4x \\  \\  =  > 2x - 4x + 12 =  - 8 \\  \\  =  >  - 2x + 12 =  - 8 \\  \\  =  >  - 2x =  - 8 - 12 \\  \\  =  >   \cancel{-} 2x =   \cancel{- }20 \\  \\  =  > 2x = 20 \\  \\  =  > x =  \frac{20}{2}  \\  \\  =  > x = 10

There are 30 students in the math class. There are 6 more boys than 1/2 the number of girls. Write a system of linear equations
Mumz [18]

Answer: the system of linear equations to represent this scenario are

b + g = 30

2b = g + 12

Step-by-step explanation:

Let b represent the number of boys in the class.

Let g represent the number of girls in the class.

There are 30 students in the math class. This can be expressed as

b + g = 30

There are 6 more boys than 1/2 the number of girls in the class. This can be expressed as

b = g/2 + 6

Cross multiplying by 2, the expression becomes

2b = g + 12

-6n-20=-2n+4 (1-3n)<br> how do you solve it?
Leona [35]
6n−20=−2n+4(1−3n)

Simplify both sides of the equation.

−6n−20=−2n+4(1−3n)

−6n+−20=−2n+(4)(1)+(4)(−3n)(Distribute)

−6n+−20=−2n+4+−12n

−6n−20=(−2n+−12n)+(4)(Combine Like Terms)

−6n−20=−14n+4

−6n−20=−14n+4

Add 14n to both sides.

−6n−20+14n=−14n+4+14n

8n−20=4

Add 20 to both sides.

8n−20+20=4+20

8n=24

Divide both sides by 8.

8n/8 = 24/8

n=3
