Question 998751

Use the equations to solve for x and y. First we'll solve for x after doing a substitution

x = 4y+3
x = 4(-2x-3)+3
x = 4(-2x)+4(-3)+3
x = -8x-12+3
x = -8x-9
x+8x = -9
9x = -9
x = -9/9
x = -1


Now find y
y = -2x-3
y = -2(-1)-3
y = 2-3
y = -1


Finally, multiply the values
x*y = (-1)*(-1) = 1



Final Answer: C) 1
