4x+y=14, 6x-3y=3 is the question​

Mathematics
1 answer:
fomenos3 years ago

Answer:

if you are being asked what the values of the x and y variables are, x=5/2 and y=4

Step-by-step explanation:

In order to solve this problem you will want to isolate one of the two variables in both equations.

I isolated the y variable in both equations so you have:

4x+y=14, when you isolate the y variable, you will get: y=-4x+14

6x-3y=3, same procedure isolate y: 6x-3=3y, now simplify so you only have y: 2x-1=y.

Now that you have the two equations which a common variable, solve them by making the two equations equal to each other like so:

-4x+14=2x-1, now you want to have all the x variable terms on one side and all the constants on the other, you will add "4x" to each side of the equal sign and then add "1" to each side to leave you with: 15=6x

now divide both sides by 6 to obtain your x value: x=15/6 simplifies to 5/2

then plug your x-value into one of the two equations we made earlier:

y=2x-1

y=2(5/2)-1

y=5-1

y=4

now you have calculated the values of your x and y values

prohojiy [21]

Answer:

t=\frac{b}{b+a}

Step-by-step explanation:

we have

t+\frac{at}{b}=1

Solve for t

That means ----> Isolate the variable t

Multiply by b both sides to remove the fraction

bt+at=b

Factor the variable t in the left side

t[b+a]=b

Divide by (b+a) both sides

t=\frac{b}{b+a}

H/6-1=-3 so what does h equal
svet-max [94.6K]

Answer:

H=-12

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

h/6-1=-3

1/6h+-1=-3

1/6h-1=-3

Step 2: Add 1 to both sides.

1/6h+1=-3+1

1/6h=-2

Step 3: Multiply both sides by 6.

6*(1/6h)=6*(-2)

H=-12

Hope this helps
