Step-by-step explanation:

The two like fractions can be set as x and y (just to use two variables).

One of them is \frac{3}{12}, though, so we can set one of the variables equal to that value (I'm just going to make y=\frac{3}{12}, it doesn't matter which variable you use).

We also know that adding the two variables gives us \frac{1}{3} so now we can make an equation.

x+y=\frac{1}{3} \\x+\frac{3}{12} =\frac{1}{3} \\x=\frac{1}{3} -\frac{3}{12} \\x=\frac{4}{12} -\frac{3}{12} \\x=\frac{1}{12}

Answer:

\frac{1}{12}

Rina8888 [55]

Answer:

x = -2

Step-by-step explanation:

-4x + 3y = 23

y = -7x - 9  //  *-3

-4x + 3y = 23

-3y = 21x -27
