- 3x + 4 - 1 = 4x is an equation.
<h3>
What is an equation?</h3>
The equal symbol (=) connects the two sides of the equation expression. 2x+1 is the left-hand side (LHS) of the equation, and 9 is the expression's right-hand side (RHS). The LHS value is equal to the RHS of the expression, as shown by the equal sign between LHS and RHS.
It is not an equation when 10x + 63 > 10. The expression's sign between the LHS and RHS in this case is not equal. We can therefore claim that not every expression is an equation. Linear inequalities are a class of expressions that fit this description.
- 3x + (4 -1) = 4x
- 3x - 4x = - 3
3x + 4x = 3
7x = 3
3/7 = x

Where is the expression in the answer it would be helpful
Answer:
6 inches per day
Step-by-step explanation:
divide 42 by 7, since there are 7 days in a week
Answer:
x ≈ 6.36
Step-by-step explanation:
Using the Sine Rule in Δ GHI
= 
, substitute values
= 
( cross- multiply )
x sin127° = 21 sin14° ( divide both sides by sin127° )
x = 
≈ 6.36 ( to the nearest hundredth )
Angles along a straight line equal 180. This means that the unmarked angle of the triangle is equal to (180-153)=27.
Angles in a triangle add to 180. This means:
(x-4)+(2x+10)+27=180
3x+33=180
3x=147
x=49
