Can you solve the system of equation using substitution y=x+8 X+y=2

1 answer:

8 0

X + y = 2
Substitute x + 8 into y
x + x + 8 = 2
2x + 8 =2
(Subtract 8 from both sides)
2x = -6
(Divide both sides by 2)
x = -3

Subsitute x = -3 into either equation to find y
x + y = 2
-3 + y = 2
(Add 3 to both sides)
y = 2 + 3
y = 5

Or y can be solved for using:
y = x + 8
y = -3 + 8
y = 5

<h3>What is Polynomials?</h3>

A polynomial is an expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables.

Here, given equation;

f(x) = (x - 1)(x + 6)

for finding the zeros of the equation we need to put.....f(x) = 0

0 = (x - 1)(x + 6)

x - 1 = 0 or x + 6 = 0

x = 1 or x = -6

Thus, The zeroes of the given polynomial is 1 and -6.
