Solve the system.

2x + y = -3

-2y = 6 + 4x

write each equation in slope-intercept form.

System: 2x + y = -3, -2y = 6 + 4x

We can solve it through elimination

-2y = 6 + 4x, y = -3 - 2x --> multiply the second equation by 2 -->

-2y = 6 + 4x, 2y = -6 - 4x --> add these two equations together -->

0 = 0: All real solutions

Slope intercept form (y = mx + d):

2x + y = -3 -->Subtract 2x--> y = -2x - 3

-2y = 6 + 4x --> Divide by -2 --> y = -3 - 2x --> y = -2x - 3

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680
