How many solutions can be found for the linear equation? 4(x + 5) - 5 = 8x + 18/ 2

A)no solutions
B)one solution
C)two solutions
D)infinitely many solutions

Respuesta :

Answer: The correct option is A.

Explanation:

The given equation is,

[tex]4(x+5)-5=\frac{8x+18}{2}[/tex]

Multiply both sides by 2.

[tex]2[4(x+5)-5]=\frac{8x+18}{2}[/tex]

[tex]8(x+5)+2(-5)=8x+18[/tex]

[tex]8x+40-10=8x+18[/tex]

[tex]8x+30=8x+18[/tex]

Subtract both sides by 8x.

[tex]30=18[/tex]

This statement is false for any value of x, therefore the system of equation have no solution and option A is correct.

Answer:

Option A is correct

No solutions

Step-by-step explanation:

The distributive property says that:-

[tex]a \cdot (b+c) = a\cdot b+ a\cdot c[/tex]

Given the equation:

[tex]4(x+5)-5 = \frac{8x+18}{2}[/tex]

Using distributive property we have;

[tex]4x+20-5 = \frac{8x+18}{2}[/tex]

⇒[tex]4x+15= \frac{8x+18}{2}[/tex]

Multiply both sides by 2 we have;

[tex]8x+30 = 8x+18[/tex]

Subtract 8x from both sides we have;

[tex]30=18[/tex] False.

For any value of x, there is no solutions for the given system of equation

Therefore, No solution can be found for the linear equation
