6 0

Answer:

one solution (0,-1)

Step-by-step explanation:

y=5x-1

-15x-3y=3

LEts solve for x  and y, Substitute  5x-1 for y in second equation

-15x-3y=3

-15x-3(5x-1)=3

-15x-15x+3=3

Combine like terms

-30x+3=3

Subtract 3 on both sides

-30x=0

Divide both sides by -30

x=0

Now plug in 0 for x in first equation

y=5x-1

y=5(0)-1=-1

So one solution (0,-1)

Jim thinks of a number (n). He adds 5 to the
Karolina [17]

Answers + Step-by-step explanation :

a) the equation should be:
7(n + 5) = 91 since you first add 5 to n and then multiply it by 7. The answer is 91 so that is on the other side of the equal sign

b) we can solve our equation to find for n, the number jim thought of

7(n + 5) = 91
I will use the distributive property.

7n + 35 = 91

Subtract 35 on both sides

7n = 56

Now divide 7 on both sides to find n

n = 8

The number Jim was thinking of was 8! this should be correct, hope this helps!
