Respuesta :

Answer:

Part 1) x=4

Part 2) x=10

Part 3) x=6

Step-by-step explanation:

Part 1) we have

[tex]-3x+10=-2[/tex]

Solve for x

That means ----> isolate the variable x

Subtract 10 both sides

[tex]-3x=-2-10[/tex]

[tex]-3x=-12[/tex]

Divide by -3 both sides

[tex]x=4[/tex]

Part 2) we have

[tex]x-7=3[/tex]

Solve for x

That means ----> isolate the variable x

Adds 7 both sides

[tex]x=3+7\\x=10[/tex]

Part 3) we have

[tex]2(x-3)=6[/tex]

Solve for x

That means ----> isolate the variable x

Divide by 2  both sides

[tex](x-3)=3[/tex]

Adds 3 both sides

[tex]x=3+3\\x=6[/tex]
