Solve 7y plus 4 equals 5y - 6?
7y + 4 = 5y - 6Subtract 4 from each side:7y = 5y - 10Subtract 5y from each side:2y = -10Divide each side by 2:y = -5
If x equals 4 and y equals 5 then 9 x plus 7y equals?
x=4 y=5 9x+7y=?? Replace: 9(4)+7(5)= 71
2x plus 6 equals -6 5x plus 7y equals 1?
if: 2x + 6 = -6 then: 2x = -12 x = -6 if: 5x + 7y = 1 then: 5(-6) + 7y = 1 7y = 31 y = 31/7
How do you solve 10x-7y equals -6 5x plus 7y equals 81 in an order pair?
10x-7y = -6 5x+7y = 81 Add both equations to eliminate y: 15x = 75 Divide both sides by 15 to find the value of x: x = 5 Substitute the value of x into the original equations to find the value of y: Therefore: x = 5 and y = 8
How do you do -9 plus 7y plus 4-3y equals Simplify Algebraic Expressions?
4y -5
Use elimination to solve the system x plus 7y equals 16 and 3x - 7y equals 4?
x+7y=16 ---------------------------1 3x- 7y=4 ---------------------------2 ------------------------------------------------------------------------------------------------------------------ 1+2 x+7y=16 3x-7y=4 4x=20 x=5 substitute x = 5 in x+7y=16 (5)+7y=16 7y=11 y=11/7
-6y plus 3 equals -7y plus 8?
-6y+3 = -7y+8 -6y+7y = 8-3 y = 5
What is 7y plus 1 equals 36?
y=5.
Solve 7y plus 4 equals 5y - 6?
7y + 4 = 5y - 6Subtract 4 from each side:7y = 5y - 10Subtract 5y from each side:2y = -10Divide each side by 2:y = -5
If x equals 2 and y equals 5 then 9x plus 7y equals?
53
If x equals 4 and y equals 5 then 9 x plus 7y equals?
x=4 y=5 9x+7y=?? Replace: 9(4)+7(5)= 71
2x plus 6 equals -6 5x plus 7y equals 1?
if: 2x + 6 = -6 then: 2x = -12 x = -6 if: 5x + 7y = 1 then: 5(-6) + 7y = 1 7y = 31 y = 31/7
X plus 7y equals 12 3x - 5y equals 10?
(5, 1)

How do you do -9 plus 7y plus 4-3y equals Simplify Algebraic Expressions?
4y -5
What is the solution of 5x - 7y equals 5?
5x - 7y = 5 (subtract both sides by 5x) -7y = -5x + 5 (divide both sides by -7) y = (5x - 5)/7 If you want to solve for y = 0, then x = 1.
Solve -2 plus 5 equals?
-2 plus 5 equals +3
