Consider this equation.


7.8 + 2(0.75m + 0.4) = -6.4m + 4(0.5m - 0.8)



Mia solved the equation and determined that m = 2. Is she correct?

She is incorrect because when substituting 2 for m the result was a true statement.

She is incorrect because when substituting 2 for m the result was a false statement.

solution for 3/4x - 12 = -18?

Answers

Answer:

x = -8

Step-by-step explanation:

Add 12 on both sides

You get 3/4x = -6

Multiply 4/3 on both sides

You get x = -24/3

Simplify and you get -8.

Answer:

x=-8

Step-by-step explanation:

The reason why x is -8 is because

The first step is to isolate the x

To isolate the x you got to add 12 to both sides

[tex]\frac{3}{4}[/tex]x-12+12=-18+12

the -12 gets canceled out by the positive twelve so all thats left now is

[tex]\frac{3}{4}[/tex]x=-18+12,-18+12 is -6 so its  [tex]\frac{3}{4}[/tex]x=-6

The second step is to divide

now you have to divide by [tex]\frac{3}{4}[/tex] on both sides

[tex]\frac{\frac{3}{4} x}{\frac{3}4} } =\frac{-6}{\frac{3}{4} }[/tex]

which [tex]\frac{3}{4}[/tex] is taken out on the left side because its divided by itself so all thats left is a one,while on the right side -6 divided by three-fourths is -8
