Question

Solve and check it :-
3x = 2x + 18​​

Answer 1

Step-by-step explanation:

3x = 2x + 18

3x - 2x(2 and 3 has the same x)= 18

x=18

Answer 2

$\bf Question$

$\sf{3x=2x+18}$

Answer:

The value of x is 18

Step-by-step explanation:

In this equation we have to find the value of x Variable : A later aur symbol used in expression that can take any value which called variable.

$\bf Back \: to \: the \: question$

$\sf{3x=2x+18}$

We combine the x term that is 3x and 2x then, we solve the question

$\implies \sf 3x - 2x = 18$

$\implies \sf 1x = 18$

$\implies \sf \underline{\boxed{ \sf x = 18}}$

$\bf Verification : -$

L.H.S (Left hand side)

$\sf Put \: value \: of \: x \: is \: 18$

$\leadsto \sf 3 \times \bf x$

$\leadsto \sf \: 3 \times 18$

$\large \leadsto \sf \: 54$

R.H.S (Right hand side)

$\sf Put \: value \: of \: x \: is \: 18$

$\leadsto \sf 2 x + 18$

$\leadsto \sf 2 \times 18 + 18$

First we have to solve BODMAS

B = Bracket

O = Of

D = Division

M = Multiple

A = Addition

S = Subtract

$\leadsto \sf36 + 18$

$\leadsto \sf54$

$\bf L.H.S = R.H.S$

Hence, verified

Required Answer :-

The value of x is 18

Additional informatioN

Monomial: An algebric expression which contains only one term is called a monomial.

For example : Expression 5x, 7x²y and -2y are monomials.

Binomial: An algebraic expression which contains two terms is called a binomial.

For example : Expression 2x+3y, 7x²-4y, -2y +3xyz are binomial.

Trinomial: An algebric expression which contains three terms is called a trinomial.

For example : Expressions 2x+3y +4z, 7x²-4y²+3z, x+x²+x³ are trinomial.

Polynomial: An algebraic expression containing one or more terms is called a polynomial.

Note : A monomial, binomial and trinomial are polynomials

Expression formed by combining variables and constants using operations addition, subtraction ,multiplication and division

Variable: A letter or symbol used in expression that can take any value is called variable.

Constant: Fixed values in the expressions are called constant.
