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]
