x=3 and y=4.
you multiply x+y=7 by neg. 2
this way you can cancel out the y factors
and get neg. 2x+x=-14+11
neg. x = neg. 3
divide both sides by neg. 1
to get x=3.
use substitution to get y=4

-5x plus 2y equals 6 -9x plus 2y equals 22?
Subtract first from second gives -4x = 16 so x = -4 and y = -7
2y plus 5y equals 10 find value of y?
2y+5y=10 7y=10 y=10/7
Simplifly 3x - 2y plus 7x plus 4y?
3x - 2y + 7x + 4y = 3x + 7x - 2y +4y = (3+7)x + (-2+4)y = 10x + 2y
What is the answer x plus 7 equals -4?
3
5-2y equals -3y - 2?
5 - 2y = -3y - 2Subtract 5 from each side:-2y = -3y - 7Add 3y to each side:y = -7
What is the answer to 4x plus y equals 8 x plus 2y equals 5?
x = 11/7 and y = 12/7
What is the answer to 5y-7 equals 2y plus 11?
5y-7 = 2y+11 (+7 to both sides) 5y = 2y+18 (- 2y from both sides) 3y = 18 (divide both sides by 3 ) y = 6 y=6
Find the slope of the line of 2x plus 2y equals 7?
The slope of the line of 2x plus 2y equals 7 is (7/2x - 1).
What is 3x equals 2y plus 7 in standard form?
3x + 2y = 7
How do you work out x plus 2y equals 7?
x+2y = 7 2y = -x+7 y = -0.5x+3.5
What is the answer to 2y plus 15 plus 7?
It is 2y + 22 = 2(y + 11)
What are the values of x and y in the equation 3x plus 2y equals 5x plus 2y equals 7 show work?
If: 3x+2y = 5x+2y = 7 which is the same as 7 = 7 = 7 Then: 3x+2y = 7 and 5x+2y = 7 Subtracting equations: x = 0 Therefore by substitution: x = 0 and y = 3.5
3x equals 2y plus 7 in standard form?
3x-2y-7=0
How do you put 3x equals 2y plus 7 in standard form?
3x = 2y + 7 The standard form is: 3x - 2y - 7 = 0
What are the exact values of x and y when 3x plus 2y equals 5x plus 2y equals 7?
If: 3x+2y = 5x+2y = 7 Then: 3x+2y = 7 and 5x+2y = 7 Subtract the 1st equation from the 2nd equation: 2x = 0 or x = o By substitution: x = 0 and y = 3.5
What is 7 plus 2y equals 15?
7+2y=15subtract 7 from each side of the equal sign2y=8divide each side by 2y=4
What is 2y-7 equals 14y plus 29 Y equals?
2y-7 = 14y+29 2y = 14y + 36 -12y = 36 -y = 3 y = -3
