You really have 2 separate equations to solve here:
1) 5(x-1) = - 20 => 5x - 5 = -20 => 5x = -15 => x = -3
2) 3y = -15 => y = -5
Answer:
The last one
Step-by-step explanation:
The last one shows x being multiplied by 0.28, which is the product
Since you are trying to isolate , you will need to remove the 13 through division:
Our answer is x = 6.
The answer is D
(5-1)/(-2-3)=4/-5
