Answer:
-3y = -4x + 6
3y = 4x - 6
y = (4/3)x - 2
y + 5 = (4/3)(x - 3)
y + 5 = (4/3)x - 4
y = (4/3)x - 9
Step-by-step explanation:
Isolate the n. First, multiply 8 to both sides
40(8) = (-5n/8)(8)
40(8) = -5n
Multiply.
320 = -5n
Isolate the n. Note the equal sign. What you do to one side, you do to the other. Divide -5 from both sides
(320)/-5 = (-5n)/-5
n = 320/-5
n = -64
-64 is your answer for n
hope this helps
Solve for p:
p/8 + 3/8 = 25/8
p/8 + 3/8 = (p + 3)/8:
(p + 3)/8 = 25/8
Multiply both sides of (p + 3)/8 = 25/8 by 8:
(8 (p + 3))/8 = (8×25)/8
(8×25)/8 = (8×25)/8:
(8 (p + 3))/8 = (8×25)/8
(8 (p + 3))/8 = 8/8×(p + 3) = p + 3:p + 3 = (8×25)/8
(8×25)/8 = 8/8×25 = 25:
p + 3 = 25
Subtract 3 from both sides:
p + (3 - 3) = 25 - 3
3 - 3 = 0:
p = 25 - 3
25 - 3 = 22:
Answer: p = 22
