Substitute answers in, a = 3 and b = 2.
(3^2 - 2^2)/(3+2)
= (9-4)/5
= 5/5
= 1

-4
X = 16y^2 + 1
x - 1 = 16y^2
(x - 1)/16 = y^ 2
( (x-1) / 16 ) ^1/2 = y
( (x-1) ^ 1/2 ) / 4 = y
Answer: They are equivalent, and x = -4/7
Step-by-step explanation:
Fist we need to see what the answers to each of these equations are
7 + 5x = 3 - 2x
Subtract 7 on each side
5x = -4 - 2x
Add 2x
7x = -4
X = -4/7
Now the second one
7 + 7x = 3
Subtract 7
7x = -4
X = - 4/7
They are equal and x = -4/7
