Question

Can anyone help me solve this equation -6+3x=-9
A)-1
B)-6
C)-5
D)-3

Answer 1

Main Objective: Get the unknown variable by itself

Answer 2

To do this we want to add or subtract the constant from both sides

Answer 3

-6 + 3x = -9
Add 6 to each side.
3x = -3
Divide 3 from each side.
x = -1

So, A) -1 is the correct answer.

Answer 4

arrange the equation so that x is on on side and the numbers on the other side

Answer 5

This will eliminate the constant from the left side of the equation. Then we can divide both sides by the coefficient to get the value of x

Answer 6

a

Answer 7

-6+3x=-9
