an = a1 +d(n-1)

a4 =a1+d(4-1)

-4 = -1+d(3)

add 1 to each side

-3 = 3d

d= -1

an = a1 +d(n-1)

an = -1 +-1 (n-1)

an = -1 -n +1

an = -n

Solve x+8y/4=9y for x

nikklg [1K]

Answer:

x = 7y

Step-by-step explanation:

x+8y/4=9y

Multiply each side by 4 to get rid of the fractions

4(x+8y/4)=9y*4

Distribute

4x +8y = 36y

Subtract 8y from each side

4x +8y-8y = 36y-8y

4x = 28y

Divide each side by 4

4x/4 = 28y/4

x = 7y
