Please Help! I'm on a Timer!
Delvig [45]

Answer:

-0.2(x - 4) = - 1.7

-0.2x + 0.8 = - 1.7

-0.2x = - 2.5

x = 12.5

Step-by-step explanation:

Solving -0.2(x - 4) = - 1.7 using the distributive property:

(-0.2)(x) + (-0.2)(-4) = - 1.7

-0.2x + 0.8 = - 1.7

Subtract 0.8 from both sides

-0.2x + 0.8 - 0.8 = - 1.7 - 0.8

-0.2x = - 2.5

Divide both sides by -0.2

\frac{-0.2x}{-0.2} = \frac{-2.5}{-0.2}

x = 12.5

Find the solution to the system of equations. 4x + 3y = –1 3x – 9y = 33 solution = ( , )
tensa zangetsu [6.8K]

Answer:

(x, y) =(2,-3)

Step-by-step explanation:

4x+3y=-1

3x-9y=33 /:3

4x+3y=-1.....(1)

x-3y=11... (2)

(1)+(2): 5x=10

x-3y=11

x=10/5

x-3y=11

x=2

2-3y=11

x=2

-3y=11-2

x=2

-3y=9

x=2

y=9/(-3)

x=2

y=-3

(x,y)=(2,-3)
