2)evaluate a+4b+2 if a=2 and be = 1

Answer 1

Answer:

1) 13(approx)

2) 8

Step-by-step explanation:

1) 7x=85

x=85/7

x=13(approx)

2) a+4b+2=0

putting a=2 and b=1

2+4(1)+2=0

2+4+2=0

8=0

Answer 2

x= 85

7

solution :

x = 85

7

2nd Answer:

Given to evaluate: a+4b+2

a=2 and b=1 (given)

put the values of a and b

2+ 4 (1) + 2

2+ 4+2

2+4+2=8 (2+4=6 +2=8)
