Equal, how do you write an expression? To write an expression, we often have to interpret a written phrase. For example, the phrase “ 6 added to some number” can be written as the expression x + 6, where the variable x represents the unknown number.
Even if, how do you simplify equivalent expressions?
What is equivalent expression?
Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value(s) for the variable(s).
3(x + 3) and 3x + 9 are equivalent expressions, because the value of both the expressions remains same for any value of x. The expressions 6(x 2 + y + 2) and 6x2 + 6y + 12 are equivalent expressions and can also be written as 6(x2 + y + 2) = 6x2 + 6y + 12.
To evaluate an algebraic expression means to find the value of the expression when the variable is replaced by a given number. To evaluate an expression, we substitute the given number for the variable in the expression and then simplify the expression using the order of operations.

BYJU'S online equivalent expression calculator tool makes the calculations and simplification faster and it displays the equivalent expression in a fraction of seconds.
BASIC Expression: An expression can be variable or constant or combination of them. Operator: An operator is a symbol or sign that specifies the certain operation to be carried out with given data or operand. For example c= a + b, where '=' and '+' are operators. ... In above example a and b are operands.
He uses some very odd expressions. The expression “to make fun of” means “to ridicule.” Judging from her expression, I think the gift was a complete surprise. We saw his expression change from angry to sad.
To solve equivalent equations, follow these five steps: Step 1 - Use the distributive property, if necessary. Step 2 - Combine like terms on the same side of the equal sign, if needed. Step 3 - Collect the variable being solved for on the same side of the equation.
To expand a bracket means to multiply each term in the bracket by the expression outside the bracket. For example, in the expression 3 ( m + 7 ) , multiply both and 7 by 3, so: 3 ( m + 7 ) = 3 × m + 3 × 7 = 3 m + 21 .
