Answer:

The equation has only one solution

Step-by-step explanation:

we have

[tex]x-10(x-2)=13-7x[/tex]

Solve for x

Distribute in the left side

Remember that

[tex](-1)(-1)=+1[/tex]

[tex]x-10x+20=13-7x[/tex]

Combine like terms in the left side

[tex]-9x+20=13-7x[/tex]

Adds 9x both sides

[tex]20=13-7x+9x[/tex]

[tex]20=13+2x[/tex]

Subtract 13 both sides

[tex]20-13=2x[/tex]

[tex]7=2x[/tex]

Divide by 2 both sides

[tex]3.5=x[/tex]

Rewrite

[tex]x=3.5[/tex]

Therefore

The equation has only one solution
