HELP!!! ASAP!

The solution to given system of equations is $(x, y) = (\frac{-15}{263} , \frac{-115}{263})$

The given equation has one solution

Solution:

Given system of equations are:

12x - 13y = 5 --------- eqn 1

x = 23y + 10 --------- eqn 2

We have to solve the system of equations by substitution

Substitute eqn 2 in eqn 1

12(23y + 10) - 13y = 5

276y + 120 - 13y = 5

263y = 5 - 120

263y = -115

$y = \frac{-115}{263}$

Substitute the above value of "y" in eqn 2

$x = 23 \times \frac{-115}{263} + 10\\\\x = \frac{-2645}{263} + 10\\\\x = \frac{-2645 + 2630}{263}\\\\x = \frac{-15}{263}$

Thus the solution to given system of equations is $(x, y) = (\frac{-15}{263} , \frac{-115}{263})$

Thus the given equation has one solution

Twelve times the quantity of a

Lunna [17]

Answer: x = 13.4

Step-by-step explanation:

We translate 'English' to 'math':

'decreased by' is subtraction

'is' means '='

12(x - 10) = 2x + 14

12x - 120 = 2x + 14

subtract 2x from each side

10x - 120 = 14

Add 120 to each side

10x = 134

Divide by 10 , to isolate the 'x'

x = 13.4

If we substitute 13.4 for 'x' back in the first equation, we get 40.8 for each side, so the equation balances.

I hope this helps.
