The system of equations to find the value of x, the first number, and y, the second number are;
<em>y = -x + 84</em>
<em>y = x² + 6</em>
<h3>System of equation</h3>
The system of equation are equations that contains more than two equation and unknown.
Let the two unknown numbers x and y
If the sum of two numbers is 84, hence;
x +y = 84
y = -x + 84
If the square of the first number is 6 more than the second number, hence;
x² = y + 6
Substitute equation 2 into 2 to have:
x² = y + 6
x² = (-x+84) + 6
x² = -x+84 + 6
x² +x+84 + 6 = 0
x² +x + 90 = 0
Hence the system of equations to find the value of x, the first number, and y, the second number are;
<em>y = -x + 84</em>
<em>y = x² + 6</em>

You can cross multiply fractions only if there is an "=" sign in the middle of the two fractions.
Step-by-step explanation:
Given:
h=7in
w=9in
l=6in
Required:
v=?
Formula:
<em>v</em><em>=</em><em>l</em><em>*</em><em>w</em><em>*</em><em>h</em>
Solution:
v=l*w*h
v=6in*9in*7in
v=54in^2*7in
v=378in^3
Hope this helps ;) ❤❤❤
Solution:
we are given that
we have been asked to find f(x).
we can find the value of f(x) by re-writing the given function in the form of f(x+3) and thereafter we will replace (x+3) by x.
we can re-write the given function as below
Hence the expression representing f(x) is f(x)=4x+3.
My calculator says bad expression.
