In a linear equation, ............power of the variable appearing in the equation is one.

1

(a)

Highest

Any value of the variable, which makes both sides of an equation equal is known as a .......... of the equation.

1

(a)

Solution

A term of an equation can be transposed to the other side by changing its.........

1

(a)

Sign

If 4t - 3 - (3t + 1)= 5t - 4, then the root of t is.....

1

(a)

4t - 3 - (3t + 1)= 5t - 4
\(\Rightarrow\) 4t - 3 - 3t - 1= 5t - 4 \(\Rightarrow\) t - 4 = 5t - 4
\(\Rightarrow\) t - 5t =-4 +4  -4t = 0 \(\Rightarrow\)  t = 0

An equation which, when reduced to a simple form, involve no power of the variable quantity higher than _______ is called a simple equation.

1

(a)

One

13z + 5 =9 is the linear equation in one variable

1

(a) False

(b) True

\(\frac { 7p }{ 3 } +6=1\) When +6 is transposed to RHS, then it \(\frac { 7p }{ 3 } =\frac { 1 }{ 6 } \)

1

(a) True

(b) False

When we add same number on both sides of an equation. Then, balance between LHS and RHS is not disturbed.

1

(a) False

(b) True

When we divide by same non-zero number on both sides (i.e. LHS and RHS) of an equation. Then, balance is disturbed.

1

(a) True

(b) False

RHS means the expression on the right of the equality sign and LHS means the expression on the left of the equality sign.

1

(a) False

(b) True
