Mathematics

Mila [183]2 years ago

Answer:

x=-4

Step-by-step explanation:

Divide both sides by 1/4

\frac{1}{4\\}(x+12)=2          (2 divided by 1/4 =8)

(x+12)=8

Subtract 12 from both sides

x=-4                 (parenthesis disappears after 12 is subtracted)

Y=-3x + 10<br> y = -2x + 6<br> Substitution method
Nutka1998 [239]

Answer:

x=4 and y=−2

Step-by-step explanation:

y=−3x+10;y=−2x+6

Step: Solve y=−3x+10for y:

Step: Substitute−3x+10foryiny=−2x+6:

y=−2x+6

−3x+10=−2x+6

−3x+10+2x=−2x+6+2x(Add 2x to both sides)

−x+10=6

−x+10+−10=6+−10(Add -10 to both sides)

−x=−4

-x/-1 = -4/-1 (Divide both sides by -1)

x=4

Step: Substitute4forxiny=−3x+10:

y=−3x+10

y=(−3)(4)+10

y=−2(Simplify both sides of the equation)
