What is the solution to this system of linear equations? 12q + 3r = 15 –4q – 4r = –44 (–18, 29) (–2, 13) (8, –1) (15, –44)

 The correct option is (B) (-2, 13).

Step-by-step explanation:  We are given to find the solution of the following system of equations :

Multiplying equation (ii) by 3, we have

Adding equations (i) and (iii), we get

From equation (ii), we get

Thus, the required solution is (q, r) = (-2, 13).

Option (B) is CORRECT.

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value

just sum

10 + 10 = 20
