Substitution

y = 2x - 12
y = -x + 3

-x + 3 = 2x - 12
+ x + x

3 = 3x - 12
+ 12 + 12
-----------------------
15 = 3x
------ ------
3 3

x = 5


y = 2(5) - 12
y = 10 - 12
y = -2


The final answer is (5,-2).

Solve the equation.<br> -21 = (m/3)<br><br> A) m = 7<br> B) m = -7<br> C) m = -63<br> D) m = 63
tiny-mole [99]

Answer:

C) m = -63 is your answer

Step-by-step explanation:

Isolate the variable (m). Note the equal sign, what you do to one side, you do to the other.

Multiply 3 to both sides

-21 = (m/3)

(-21)(3) = (m/3)(3)

m = (-21)(3)

Combine like terms. Simplify.

m = -21 * 3

m = -63

C) m = -63 is your answer
