Question 12 • Mathematics I

What is the solution to this system of linear equations? 7 x minus 2 y is equal to negative 6; 8 x plus y is equal to 3

Answer
A
15 comma negative 1
B
negative 6 comma 3
C
1 comma negative 5
D
0 comma 3

Explanation

From 8x + y = 3, solve for y: y = 3 - 8x. Substitute into 7x - 2y = -6: 7x - 2(3 - 8x) = -6, which simplifies to 23x = 0, so x = 0. Then y = 3, so the solution is 0 comma 3, choice D.
