Find the solution to the system of equations: x + 3y = 7 and 2x + 4y = 8

1. Isolate x in the first equation:

2. Substitute the value for x into the second equation:

3. Solve for y:

4. Substitute y into either original equation:

5. Write the solution as an ordered pair:

x = 7 – 3y

2(7 – 3y) + 4y = 8

14 – 6y + 4y = 8

14 – 2y = 8

–2y = –6

y = 3

x + 3(3) = 7

Answer 1

Answer:

x + y = 1

Explanation:

X + 3y = 7

2x + 4y = 8

2x - x = x (1x)

4y - 3y = y (1y)

8 - 7 = 1

x + y = 1

Explain how the angle-angle-side congruence theorem is an extension of the angle-side-angle congruence theorem.

Answers

Answer:

The interior angle measures of a triangle add up to 180 degrees. Thus, if you are given angle-angle-side, you can solve for the third angle measure and essentially have angle-side-angle because the given side will now be the included side.

Explanation:

In congruent triangles, 2 angles and the enclosed side of another triangle are equivalent to the similar angles and side of some other triangle, the extension of angle-angle-side.

What is angle-side-angle?

The Angle-Side-Angle defines that if 2 consecutive angles as with a non-included side of one triangle are appropriate to the related 2 consecutive angles and the non-included side of the other triangle, then the 2 triangles are congruent.

This congruent triangle is called as the angle-side-angle, and they form, the extension of angle-side-angle congruence theorem.

A triangle is measured by the inferior angle that add up to 180 degrees. Thus, in given angle-angle-side, solve for the 3rd angle measure and fundamentally have angle-side-angle, as the given side will now be the enclosed or included side.

Therefore, it is called as the extension of angle-side-angle congruence theorem.
