Question

Who will give anewer with explaination I will mark as brillant​

Answer 1

Step-by-step explanation:

a. 7x = 28

Here 7 is on LHS in multiplication for

So move 7 to RHS. If u go from LHS to RHS , sign changes

× becomes ÷

÷ becomes ×

+ becomes -

- becomes +

Here 7 is in (×) sign as [7×x = 28]

So if you move it will become x = 28÷7 ( sign changes)

So x= 4 as 28/7 = 4

f. 5(x+ 4) = 25

Now first multiply 5 by x and then 4 , bracket will be solved

So 5×x + 5×4 = 25

So 5x +20 = 25

Now first move 20 on RHS , as sign is plus(+) it will become (-)

So 5x= 25-20

5x = 5

Now move 5 on RHS

SO x = 5÷5 , x= 1

Rest all try by yourself
