Question

1. Verify the following:
(i) 18 x [9+(-7)] = 18 x 9 +18 (-7)
(i)
12​

Answer 1

Explanation:

Let's solve your equation step-by-step.

18x(9−7)=18x(9)+(18)(−7)

Step 1: Simplify both sides of the equation.

18x(9−7)=18x(9)+(18)(−7)

36x=162x+−126

36x=162x−126

Step 2: Subtract 162x from both sides.

36x−162x=162x−126−162x

−126x=−126

Step 3: Divide both sides by -126.

−126x/−126=−126/−126

x=1

Answer:

x=1

Answer 2

Answer:

Explanation:

18×[9+ (-7)]=18 ×9+18 (-7)

Step-by-step explanation:

First we will take 18 as common of right hand side

So we will get ,

18×[9+ (-7)]=18×[9+(-7)]

            OR

LHS =18×[9+(-7)]

=18×[9-7]

=18×2

=36

RHS=18×9+18(-7)

=162-126

=36

RHS=LHS
