Answer:
B. 1
Step-by-step explanation:
Since one of the equations is already solved for y, let's use substitution to find out the answer. We will sub in 4x - 3 for y into the first equation:
3x - 4(4x - 3) = 12 and
3x - 16x + 12 = 12 and
-13x = 0 so
x = 0.
Now we will plug in 0 for x into the other equation to solve for y:
y = 4(0) - 3 and
y = 0 -3 so
y = -3
The solution set as a coordinate pair for this system is (0, -3), the only solutiion.
