Question

Solve the linear Equation . -10x -3= -10 -3x​

Answer 1

-10x-3= -10-3x

-10x+10x-3= -10x+10x-3x

-3=-3x

divide by -4 for -3 and -3x

-3/-3= -3x/-3

1=x

x= 1

check answer by using substitution method

-10x-3= -10-3x

-10(1)-3=-10-3(1)

-13=- 13

Answer is x= 1

Answer 2

-10x - 3 = -10 - 3x

Bring -10x to the other side by adding it to both sides

(-10x + 10x) - 3 = -10 + (-3x + 10x)

0 - 3 = -10 + 7x

-3 = -10 + 7x

Bring -10 to the oposite side by adding 10 to both sides

-3 + 10 = (-10 + 10) + 7x

7 = 0 + 7x

7 = 7x

Isolate x by dividing 7 to both sides

7/7 = 7x/7

x = 1
