In the expression 2x+12 what is the coefficient

2

Step-by-step explanation:

2 is the coefficient, it is being multiplied by x.

X is the variable in this equation its value is not set and it is unknown.

12 is the constant, its value does not change because it isnt being multiplied/divided by anything.

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3
