2x+3y=11

4x+2y=10

multiple the top equation by -2

-4x-6y=-22

4x+2y=10

-4y= -12

y=3

then plug 3 for y so 2x+9=11

2x=2

x=1 and y=3

Solve this linear equation <br> 2(x+6)&lt;3x+8
FinnZ [79.3K]

Answer:

x > 4

Step-by-step explanation:

Given

2(x + 6) < 3x + 8 ← distribute left side

2x + 12 < 3x + 8 ( subtract 3x from both sides )

- x + 12 < 8 ( subtract 12 from both sides )

- x < - 4

Multiply both sides by - 1, reversing the symbol as a result of multiplying by a negative quantity.

x > 4

Can anyone help me with this?
erma4kov [3.2K]

Answer:  16y² - x²

Step-by-step explanation:  The - sign means a difference, so the choices with + signs are eliminated (though 64x² and 9 are squares)

10 is not a square so that one is eliminated (though the y² and the 4x² are squares)

16 is the square of 4, y² is the square of y, and x² is the square. That expression shows a difference of squares.
