How do you do -9 plus 7y plus 4-3y equals Simplify Algebraic Expressions?
4y -5
2x - 3y equals 4 and x plus 4y equals -9?
(-1,-2)
Solve this equation using subtitution 2x-3y equals 4 and x plus 4y equals -9?
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,

4y + 7 < 3y + 9 4y - 3y < 9 - 7 y < 2
4y plus 4 equals 3y-5?
4y + 4 = 3y - 5 y = -9
4y plus 7 greater than 3y plus 9?
open circle on +2, arrow going right.
Simplify the algebraic expression 7x squared minus 4y plus 3x squared plus 5y plus 2 and evaluate it for x equals 3 and y equals 9?
7(3y-2)-(-4y+9)
What is 7 plus 8y-3y plus 2?
7 + 8y - 3y + 2 =7 + 2 + 8y - 3y = 9 + 8y - 3y = 9 + 5y
How do you do -9 plus 7y plus 4-3y equals Simplify Algebraic Expressions?
4y -5
What is the answer to 5x - 4y plus 9y plus x -9 plus 7?
5x-4y+9y+x-9+7 = 5x + x - 4y + 9y - 9 + 7 = 6x + 5y - 2 ■
2x - 3y equals 4 and x plus 4y equals -9?
(-1,-2)
Solve this equation using subtitution 2x-3y equals 4 and x plus 4y equals -9?
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,
Solve this system of equation using substitution 2x -3y equals -4 and x plus 4y equals -9?
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
What is the order pair for 2x - 3y equals 4 and x plus 4y equals -9?
The ordered pair is (-1, -2).
4times y plus 6 plus 9?
4y+6+9=4y+15
