5x = 15
x = 3
3(3) - 5y = -16
9 - 5y = -16
5y = -16 - 9
5y = - 25
y = - 5
(3, -5)
Another possible solution would be f(8)=4. I basically doubled it.
The partial products that Lucas would need to solve this problem would be 3,740 and 187,000 if you are multiplying 374 on the top column and 510 on the bottom column. Or, the partial products Lucas would need is 2,040 and 35,700 and 153,000. Both partial products combination added together would be 190,740.
6(-4x - 7) - 4(x - 6) Distribute 6 into (-4x - 7) and -4 into (x - 6)
(6)(-4x) + (6)(-7) + (-4)x + (-4)(-6) (two negative signs cancel each other out and become positive)
-24x - 42 - 4x + 24 Combine like terms(terms that have the same variable and power/exponent)
-24x - 4x - 42 + 24 (I rearranged the terms to be next to their like term)
-28x - 18 Your answer is D
Step-by-step explanation:
2y+3=5x-18
swap both sides
5x-18=2y+3
add 18 to both sides
5x-18+18=2y+3+18
5x=2y+21
divide both sides by
5x/5=2y+21/5
X=2y+21/5
