If Jiri is x, Pamela is x -5, and tehri ages combined would be 35 so;
x + x-5 = 35
collect the like terms
2x-5 = 35
add five to both sides
2x= 40
divide both sides by 2
x=20
Jiri's age is 20
Answer:
x = - 1 and x = 5
Step-by-step explanation:
Given
(x - 3)² + 2(x - 3) - 8 = 0
Let u = x - 3, then
u² + 2u - 8 = 0 ← solve for u
(u + 4)(u - 2) = 0 ← in factored form
Equate each factor to zero and solve for u
u + 4 = 0 ⇒ u = - 4
u - 2 = 0 ⇒ u = 2
Convert back to x, that is
x - 3 = - 4 ( add 3 to both sides ) ⇒ x = - 1
x - 3 = 2 ( add 3 to both sides ) ⇒ x = 5
Answer:
y = -5/2x + 10
Step-by-step explanation:
Step one: Add -5x to both sides.
5x + 2y + -5x = 20 + -5x
2y = -5x + 20
Step two: Divide both sides by two.
2y/2 = -5x + 20/ 2
y = -5/2x + 10
Hope my answer help.
24 the answer is 24
(just because i dont have enough characters soooooo LOLOLOLOLOL)
X+3= -x-5
x+x= -3-5
2x= -8
x= -4
1-2x= -x-3
1+3=2x-x
x=4
x-2= -3x+2
x+3x=2+2
4x=4
x=1
