Question

15. If x = -2, y = 6 is solution of equation 3ax + 2y = 6, then find the value of b from 2(a - 1) +2(3b - 4) = 4.

pls ans real quick​

Answer 1

Answer:

3×-2×a+2×6=6

-6a+12 =6

a=1

2(1-1)+2(3b-4)=4

6b-8=4

6b=12

b=2

Answer 2

Step-by-step explanation:

3(-2)a+2(6)=6

-6a+12=6

-6a=6-12

-6a=-6

a=-6/-6

a=1

2(1-1)+2(3b-4)=4

2+6b-8=4

6b-6=4

6b=4+6

6b=10

b=10/6

b=5/3
