Answer: y=-2/5x-3/5
Step-by-step explanation:
y=-2/5x+3
x=-2/5y+3
x(5y+3)=-2/5y+3×5y+3
x(5y+3)=-2
Devide by X on both sides
5y+3=-2/x
5y=-2/x-3
y=-2/5x-3/5
You can use mental math to perform the following addition by knowing that certain numbers equal a certain number. for instance, you know that 9+2 is equal to 11. you don't need a calculator to solve that. then you know that 1+8 is equal to 9.since you are adding 11 you know that the answer is 19. you can use that to answer to following equation.
