Check that x=2 and y=5 is a solution of both equations below: X+2y=12 3x+6y=36 *

melamori03 [73]

Answer:

yes

Step-by-step explanation:

Substitute x = 2 and y = 5 into the left side of the equations and if equal to the right side then they are a solution.

x + 2y = 2 + 2(5) = 2 + 10 = 12 ← True

3x + 6y = 3(2) + 6(5) = 6 + 30 = 36 ← True

Thus x = 2, y = 5 is a solution to both equations

Solve by substitution 3x-4y=-4 y=2x-4

dybincka [34]

Answer:

x=4 and y=4

Step-by-step explanation:

From first function we have:

$3x - 4y = - 4 \\ 4y = 3x + 4$

And from the second one:

$y = 2x - 4 \\ 4y = 8x - 16$

Substitute them:

$4y = 3x + 4 \\ 4y = 8x - 16 \\ \\ 0 = - 5x + 20 \\ x = 4 \\ y = 4$
