Solve the system of equations by subsitution.
b = 4a +2
12a - 3b = -6

infinite solution

Step-by-step explanation:

hello

we substitute b = 4a + 2 in the second expression

12a -3*(4a+2) = -6

<=> 12a -12a -6 = -6

<=> -6 = -6

which is always true

so there is infinite solution

hope this helps

answer: they are supplementary angles

step-by-step explanation: 161+19=180. supplementary angles equal 180 degrees
