The sum of the given expression expressed as a quadratic equation is 10x^2 + 13x + 11
<h3>Sum of expressions</h3>
Expressions are equations separated by mathematical signs. This expressions are known to contains certain unknowns
Given the following expression
10x^2 +7x+6 and 6x + 5
We are to take the sum of both expression to have:
f(x) = 10x^2 +7x+6 + 6x + 5
Collect the like terms
f(x) = 10x^2 + 7x + 6x + 6 + 5
f(x) = 10x^2 + 13x + 11
Hence the sum of the given expression expressed as a quadratic equation is 10x^2 + 13x + 11

Question;
Me pueden ayudar a resolver por método de sustitución porfa.
Translation: Can you help me to solve by please substitution method.
{5x+7y=-1
{-3x+4y=-24
Step-by-step explanation:
Given the simultaneous equation.
5x+7y=-1 .....1
-3x+4y=-24 .....2
From equation 2, making y the subject of formula.
4y = -24 + 3x
y = (-24+3x)/4 ...... 3
Substituting the equation 3 into equation 1
5x+7((-24+3x)/4) = -1
Multiply through by 4
20x + 7(-24+3x) = -4
20x - 168 + 21x = -4
41x -168 = -4
41x = -4 + 168
41x = 164
x = 164/41 = 4
x = 4
Substituting x = 4 into equation 3
y = (-24+3(4))/4
y = (-24+12)/4
y = -12/4
y = -3
