Solve for x in the second equation first

kumpel [21]3 years ago

Answer:

Solve for x in the second equation.

Step-by-step explanation:

To solve a system of equations by substition you have to solve one of the equations for X or Y and then substitute that value on the X of the other equation, if you want to avoid fractions, you can use the x of the secon equation, like this:

6x+18y=24\\6x=24-18y\\x=\frac{24-18y}{6} \\x=4-3y

So by solving X for the second equation you avoided fractions when substituting the value for X on the first equation.

How can I solve this?
jok3333 [9.3K]

The 3 inside angles need to equal 180 degrees.

Angle K is given as 48 degrees.

Angle M would be 90 degrees.

Angle J = 180 - 90 - 48 = 42

Angle J = 42 degrees
