Step 1:

Wright the equation
________________________________
Step 2:

Transfer the power of y ie ¹² up to subtract it
________________________________
Step 3:

by subtracting the powers we get 0
________________________________
Step 4:

so the results comes 1 because anything ⁰=1

Answer:
x = 4
Step-by-step explanation:
x + 4(x+5) = 40 (Given)
x + 4x + 20 = 40 (Distribute the 4 into the x and 5)
5x + 20 = 40 (Add like terms)
5x = 20 (Subtract 20 on both sides)
x = 4 (Divide 5 on both sides)
6+9=15
y+9=x
x=30
y+9=30
y=21
Answer:
1 4/6
Step-by-step explanation:
The slope of the line (m) = 3/1 = 3
and the y intercept is at (0,3) that is y = 3 so b = 3
using the slope intercept form y = mx + b
m = 3 and b = 3
so answer is y = 3x + 3
