Question

How to find value of any algebraic equation​

Answer 1

Answer:

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.

Answer 2

Answer:

When solving an equation it is important to find the value of one letter.

Let's solve the equation 3x + 4 = 10

To remove the + 4 we complete the inverse (opposite) operation by subtracting the 4.

3x = 10 – 4

That gives us 3x = 6 (3 loaves cost £6)

To work out the cost of one loaf we divide both sides of the equation by 3.

x = 6 ÷ 3

So x = 2 (one loaf costs £2)
