Answer:
x = 11
Step-by-step explanation:
Simplify [tex]2(x-3)+7[/tex]
Apply the distributive property.
[tex]2x - 6 + 7= 23[/tex]
[tex]2x+1=23[/tex]
Move all terms not containing x to the right side of the equation.
Subtract 1 from both sides of the equation.
[tex]2x =23-1[/tex]
[tex]2x=22[/tex]
Divide each term by 2 and simplify
[tex]\frac{2x}{2} = \frac{22}{2}[/tex]
Cancel the common factor of 2
[tex]x = \frac{22}{2}[/tex]
Divide 22 by 2
[tex]x = 11[/tex]
No 4 is not a solution of the equation becouse it would be an inproper solution
No... it’s not.
Let’s substitute x = 4 in a given equation
LHS = 2(x-3) + 7
= 2 (4-3) + 7 ( substituting x = 4)
= 2(1) + 7
= 2 + 7
= 9
RHS = 23
Here, as we can see by substituting x = 4, in the given equation, LHS ≠ RHS.
Hence, it’s not a correct solution
