adelina 88 [10]3 years ago
6 0

Answer:

y = 8/7x -18/7

Step-by-step explanation:

8x-7y=18

Subtract 8x from each side

8x-8x-7y=-8x+18

-7y = -8x+18

Divide each side by -7

-7y/-7 = ( -8x+18)/-7

y = 8/7x -18/7

1 and 2 are supplements, 3 and 4 supplements and 1 =4. prove 2=3<br>​
Ne4ueva [31]

Step-by-step explanation:

Supplementary angles are angles that have the sum of their angles to be 180°. Hence if <1 and <2 are supplements, then <1+<2 = 180°.... 1

Similarly if <3 and <4 are supplements, then <3+<4 = 180° ....... 2

Equating the left hand side of both equations since they are both equal to 180°, we will have;

<1+<2 = <3+<4 ....... 3

From the question we are told that <1 = <4, substituting this condition into equation 3;

From 3; <1+<2 = <3+<4

<4+<2 = <3+<4 (since <1 = <4)

subtract <4 from both sides

<4+<2 -<4= <3+<4 -<4

<2 = <3 (Proved!)
