18 + 70 ie 87

It is: 7x+10y

-17 + y,,must be equals to..-17y..

-5y2+3x+2y

It is: 3x+10y+5 simplified

It's a linear expression in two unknowns.It can be simplified a little bit:18x + 14y + 3x - 10y = 21x + 4y

(4, 5)

2x + 3y = 17 3x + 4y = 24 (2x + 3x) + (3y + 4y) = (17 + 24) 5x + 7y = 41

3x + 4y = 5x - 2y = 5leads to:x = 5 + 2ySo:3(5 + 2y) + 4y = 515 + 10y = 510y= -10y=-1and therefore if y = -1 then x = 3.

3x = 24, x = 8

no

If x = 8 and y = 10 then it is 44.

The value of x is -4

The answer is: x-y = 11 3x+10y = -6

It is an equation and the value of x is 13/3

3x plus 9 equals what?

3x + 2 = 3x + 6 This is not possible.

-5(x + 2y) -3x + 8y + 5 = -5x -10y -3x + 8y + 5 = -8x -2y + 5

-2x-10y-12+3xy=4Put all x's to the other side and the ones with y's on the other:-10y+3xy=4+2x+12-10y+3xy=16+2xNow you factor a y from the side with the y's:y(-10+3x)=16+2xDivide both sides by (-10+3x):y=(16+2x)/(-10+3x)

(2, -1)

Their graphs are.

8x - 5 + 3x + 17 = 155% 11x + 12 = 1.55 11x = 1.55 - 12 = -10.45 x = - (10.45/11) = - 0.95

3x + 5x = 348x = 34x = 34/8x = 17/4 orx = 4.25

-3x-8+4x=17(-3x+4x)-8=17 ;combine like terms(x)-8=17 ;add 8 to both sidesx=25
