Answer:
x = -1 and y = -1
Step-by-step explanation:
Solve 3x+3y=−6;−x+y=0
Steps:
I will solve your system by substitution.
−x+y=0;3x+3y=−6
Step: Solve−x+y=0for y:
−x+y+x=0+x(Add x to both sides)
y=x
Step: Substitutexforyin3x+3y=−6:
3x+3y=−6
3x+3x=−6
6x=−6(Simplify both sides of the equation)
6x
6
=
−6
6
(Divide both sides by 6)
x=−1
Step: Substitute−1forxiny=x:
y=x
y=−1
Answer:
x=−1 and y=−1
Answer:
(x-1)(x-1)
Step-by-step explanation:
hello :
(x+2) ²-6 (x+ 2) +9 =(x+2) ²-2×(<em>3</em>) (x+ 2) +<em>3²</em>
by identity : (a-b)² = a²-2ab+b²
let : a=x+2 and b= <em>3</em>
(x+2) ²-6 (x+ 2) +9 =(x+2) ²-2×(<em>3</em>) (x+ 2) +<em>3²=</em> ((<em>x+2)-3</em>)<em>²= (</em>x+2-3)² = (x-1)²=
(x-1)(x-1)
