What is the solution to the following system of equations?
Mrac [35]

Answer:

<h2>x = 3, y = -1 ⇒ AB</h2>

Step-by-step explanation:

\left\{\begin{array}{ccc}x-3y=6&\text{multiply both sides by (-2)}\\2x+2y=4\end{array}\right\\\\\underline{+\left\{\begin{array}{ccc}-2x+6y=-12\\2x+2y=4\end{array}\right}\qquad\text{add both sides of the equations}\\.\qquad\qquad8y=-8\qquad\text{divide both sides by 8}\\.\qquad\qquad y=-1\\\\\text{Put the value of y to the first equation:}\\\\x-3(-1)=6\\x+3=6\qquad\text{subtract 3 from both sides}\\x=3

Please help ;-; <br> Solve for the simultaneous equation….<br> 5x+y=17<br> X+y=3
Svetach [21]

<u>Given Equation</u>:-

  • 5x+y=17 . . . . . . . . 1
  • x+y=3 . . . . . . . . . . 2

<u>To find</u> :

  • value of x
  • value of y

<u>Solution</u> :

<u>Let's start with equation 2</u>:-

x + y = 3

y = 3 - x

Put the value of y in Equation 1

  • 5x+y=17
  • 5x + (3 - x) = 17
  • 5x - x + 3 = 17
  • 4x + 3 = 17
  • 4x = 17 - 3
  • 4x = 14
  • x = 14/4
  • x = 7/2
  • x = <em>3.5</em>

<u>Now Let's find value of y</u><u>:</u>

put the value of x in equation 2:

y = 3 - x

y = 3 - 3.5

y = <em>0.5</em>

NEED HELP ASAP PLEASE!! The provided diagram of triangle ABC will help you to prove that the base angles of an isosceles triangl
Lunna [17]

Answer: The proof is mentioned below.

Step-by-step explanation:

Here, Δ ABC is isosceles triangle.

Therefore, AB = BC

Prove: Δ ABO ≅ Δ ACO

In Δ ABO and Δ ACO,

∠ BAO ≅ ∠ CAO  ( AO bisects ∠ BAC )

∠ AOB ≅ ∠ AOC ( AO is perpendicular to BC )

BO ≅ OC ( O is the mid point of BC)

Thus, By ASA postulate of congruence,

Δ ABO ≅ Δ ACO

Therefore, By CPCTC,

∠B ≅ ∠ C

Where ∠ B and ∠ C are the base angles of Δ ABC.
