Solve.
Pavlova-9 [17]

Answer:

  (2, -3)

Step-by-step explanation:

Apparently, the equations are supposed to be ...

  • 4x +y = 5
  • 3x +y = 3

The solution for x can be found by subtracting the second equation from the first:

  (4x +y) -(3x +y) = (5) -(3)

  x = 2 . . . . . . . matches the second answer choice

Y can be found from either equation:

  y = 5 - 4x . . . . . subtract 4x from the first equation

  y = 5 -4(2) = -3

The solution is (x, y) = (2, -3).

          Hi my lil bunny!

A) Let's solve for x.  2x + 3y = 40

Step 1: Add -3y to both sides.

2x + 3y + -3y = 40 + -3y

2x = -3y + 40

Step 2: Divide both sides by 2.

\frac{2x}{2} = \frac{-3y + 40}{2}

x = \frac{-3}{2} y + 20

Answer : \frac{-3}{2} y + 20

~~~~~~~~~~~~~~~~~

B) Let's solve for x. 5x + 2y = 30

Step 1: Add -2y to both sides.

5x + 2y + -2y = 30 + -2y

5x = -2y + 30

Step 2: Divide both sides by 5.

\frac{5x}{5} = \frac{-2y + 30}{5}

x = \frac{-2}{5} y + 6

Answer : \frac{-2}{5} y + 6
