Evaluate .

2x+(−6)∙(y+1) for x=−1.5 and y=−3

To start off, plug in -1.5 for x. The equation is now simplified to 2(-1.5) * (y+1).
Then plug in -3 for y. The equation is now 2(-1.5) * (-3+1). Now it's time to solve now. 2 times -1.5 would be -3, I got that by simply multiplying 1.5 times two and then adding a negative sign and the decimal place. Then, -3 times the solution to -3 + 1, which is -2, which is simply subtracting the larger number by the smaller and adding back the sign of the larger number. So in conclusion, -3 * -2 would get you positive 6, because two negatives multiplied together end in a positive. Hope this helps!
