Question

This needs to be answered for a number line -9=4x+3

Answer 1

Answer:

X=-3

Step-by-step explanation:

To find the unknown variable: X, we need to see how mich 4x equals to. to do this, we must first subtract 3 from both sides of the equation. The left side will be left with -12, and the right side will be left with 4x. This means:

-12=4x So...

x=-3

To check if this is right, you can subsitute this back into the equation.

4 times -3= -12. -12=3=-9
