Answer:
(- 
, 4 )
Step-by-step explanation:
Given the 2 equations
3x + 8y = 28 → (1)
3x + 2y = 4 → (2)
Subtracting (2) from (1) term by term will eliminate the x- term
(3x - 3x) + (8y - 2y) = (28 - 4), that is
6y = 24 ( divide both sides by 6 )
y = 4
Substitute y = 4 into either of the 2 equations and solve for x
Substituting into (1)
3x + 8(4) = 28
3x + 32 = 28 ( subtract 32 from both sides )
3x = - 4 ( divide both sides by 3 )
x = -
Solution is (- , 4 )

Answer:
The answer is
<h3>
</h3>
Step-by-step explanation:
x² + x - 5 = 0
Using the quadratic formula
That's
<h3>
</h3>
From the question
a = 1 , b = 1 , c = - 5
Substitute the values into the above formula and solve
We have
<h3>
</h3>
We have the final answer as
<h3>
</h3>
Hope this helps you
X - 4 = y^2
Since you want y to the first power you have to take the square root of y^2.
If you take the square root of the right side you also must take the square root of the left side.
+ - sqrt (x-4) = y
y = sqrt (x - 4)
and y = - sqrt (x - 4)
