Question

pls its emergency help me ..
pls answer que 1 , 2.​

Answer 1

Q6. 3y=ax+7

we know y value is 3 and X value will be 4. input

3×3=a×4+7

(9-7)/4=a

1/2=a

checking:

3(3)=(X/2)+7

9-7=X/2

2×2=X

X=4 so it works.

Q7. 30+7x+3x=180(angles are supplimentary)

10x=150

X=15

hope this helps

Answer 2

Step-by-step explanation:

6. x=3 y=4

3y = ax+7

3(4) =a(3) + 7

12 = 3a +7

12-7 = 3a

5 = 3a

a = 5/3

7. 30 +7x+3x =180

10x = 180-30

x = 150/10

x = 15

Or 50+x =180 [ same side of the transversal]

x= 180- 50

x = 130

y= 130
