Question

B) (6a + a) : 13 = 14;r) 48 : (9b - b) = 2.​

Answer 1

1) (6a+a)÷13=14

7a÷13=14

7/13a=14

a=26

2) 48÷(9b-b)=2

48÷(8b)=2

48/8b=2

6/b=2

6=2b

b=3

Answer 2

To solve these equations for the variable 'a' and 'b', you'll need to isolate the variable on one side of the equation. Let's solve each equation step by step:

B) (6a + a) / 13 = 14

Combine like terms on the left side of the equation:

(7a) / 13 = 14

Now, to solve for 'a', multiply both sides of the equation by 13 to isolate 'a':

7a = 14 * 13

7a = 182

Now, divide both sides by 7 to find the value of 'a':

a = 182 / 7 a = 26

So, the solution for 'a' is a = 26.

R) 48 / (9b - b) = 2

Simplify the denominator on the left side of the equation:

48 / (8b) = 2

Now, to solve for 'b', first multiply both sides of the equation by 8b to isolate 'b':

48 = 2 * 8b

48 = 16b

Now, divide both sides by 16 to find the value of 'b':

b = 48 / 16 b = 3

So, the solution for 'b' is b = 3.
