x+19= 26
x+19-19= 26-19
x= 7
Check answer by using substitution method
x+19= 26
7+19= 26
26= 26
Answer is x= 7 (D.)
To find the solution we need to solve for x
We need to get x alone to solve for x.
To remove any number, always do the opposite operation
Opposite of +19 is -19
To remove +19 , subtract 19 from both sides
x+19=26
x+19 -19 =26-19 =7
x=7
So the value of x=7
The solution to this equation Option D. x=7
An equation is a mathematical statement that is made up of two expressions connected by an equal sign. For example, 3x – 5 = 16 is an equation. Solving this equation, we get the value of the variable x as x = 7.
There are three major forms of linear equations: point-slope form, standard form, and slope-intercept form.
An equation is a mathematical statement that two things are equal. It consists of two expressions, one on each side of an 'equals' sign. For example x=y is an equation where two expressions x and y are equal. Whereas f(x)=x is a function with variable x and hence f(x)=x is not an equation.
