Question

Find the value of a & b​

Answer 1

The values of the variables a and b are:

a = 23

b = 10

Answer 2

a = 23

b = 10

Explanation:

The general formula is

y = 3x + 5

Just to check, let x = 2

y = 3*2 + 5

y = 6 + 5

y = 11

And a confirmation check

x = 3

y = 3*3 + 5

y = 9 + 5

y = 14

So for a

x = 6

y = 6*3 + 5

y = 18 + 5

y = 23

For b, you know y

35 = 3x + 5

- 5 -5 Subtract

30 = 3x Divide by 3

30/3 = 3x/3

x = 10
