y = 3

4y + 4 = 3y - 5 y = -9

(7, 4)

(0,-4)

If y + 3y + 10 = 70, then 4y + 10 = 70, and 4y = 60. We then find that y = 60/4 = 15.

x = - 4 and y = 0

(-1,-2)

4 - 3y - y = 04 - 4y = 0add 4y to both sides4 = 4ydivide both sides by 4y = 1

x=-2, y=2

"3y + 4y = 19" is a mathematical sentence involving one unknown, y. If you wanted it solved (ie you meant to ask; "What is y in 3y plus 4 y equals 19"), then: 3y + 4y = 19 → (3 + 4)y = 19 → 7y = 19 → y = 19/7 = 2 5/7 ≈ 2.71

4y -5

The ordered pair is (-1, -2).

Since 2x-3y=4y=8 we can say that 4y=8 therefor y=2 We can also say that 2x-3y=4y and as y=2 2x-6=8 so 2x=14 and x =7 so y=2 and x=7

2(-2)-3y=6 which is equal to -4 -3y = 6 which is equal to -3y = 10 which is equal to y = -(10 / 3) = -3.333...

y = 4, x = 6

2x - 3y = -4x + 4y = -9from the second equation x = -9-4y , substitute it in the first equation.2(-9-4y)- 3y= -4-18-8y-3y = -4-18-11y = -4-11y = -4+18-11y = 14y = -14/11now, solve for x :x = -9-4yx = -9-4(-14/11)x = -43/11

2x-3y = 4 x+4y = -9 => x = -9-4y Substitute x = -9-4y into the top equation: 2(-9-4y)-3y = 4 -18-8y-3y = 4 -8y-3y = 4+18 -11y = 22 Divide both sides by -11 to find the value of y: y = -2 Substitute the value of y into the original equations to find the value of x: Therefore: x = -1 and y = -2 Remember that the product of a minus times a minus is equal to a plus when working out the original equations,

7y-3y-14=14 4y-14=14 4y-14+14=14+14 (adding 14 on both side) 4y=28 (4y)/4=28/4 (dividing by 4 on both side) y=28/4=7

Do you want the solutions to the equations? If so then: x = 7 and y = 4

y=4

3y=7y+24.4 First, try to get all the y-terms on the same side of the equation. Easily done here by subtracting 7y from both sides 3y-7y=7y-7y+24.4 -4y=24.4 Now divide by -4 -4y/-4=24.4/-4 y=-6.1

y(3y^2 - 12y + 4)

5y + 4 = 4y + 5 y + 4 = 5 (subtracting 4y from both sides)y = 1 (subtracting 4 from each side)
