Step-by-step explanation:
Given
2a + b = 6......equation 1
a - 6 = b
a = b + 6........equation 2
Putting equation 2 in equation 1
2 ( b + 6 ) + b = 6
2b + 12 + b = 6
3b = 6 - 12
3b = - 6
b = - 6 / 3
Therefore b = - 2
Now
a = - 2 + 6 = 4
hope it will help :)
Answer:
a = 4
b = -2
2a + b = 6
a - b = 6
Elimination
________+
3a = 12
a = 12/3
4 - b = 6
-b = 6 - 4
-b = 2
