Find the answers in 4x plus 3y equals 12 7x plus 3y equals 21?
x = 3 and y = 0
Solve 2x plus 3y equals 12 when x equals 1.45?
2x + 3y = 12 x = 1.45, so 2 * 1.45 + 3y = 12 2.9 + 3y = 12 3y = 12 - 2.9 = 9.1 y = 9.1/3 = 3.0333... or 91/30 or 3 1/30.
What is the slope of 3x plus 3y equals 12?
The slope is -1. 3x+3y=12 Subtract 3x 3y=-3x+12 Divide by 3 y=-x+4
What is the solution of 3x plus 2y equals 13 and 2x plus 3y equals 12?
x = 3 and y = 2
Can anyone help solve this problem 7y plus 2 equals 3y-10?
7y = 3y - 12 4y = -12 y = -3
Find the answers in 4x plus 3y equals 12 7x plus 3y equals 21?
x = 3 and y = 0
Solve 2x plus 3y equals 12 when x equals 1.45?
2x + 3y = 12 x = 1.45, so 2 * 1.45 + 3y = 12 2.9 + 3y = 12 3y = 12 - 2.9 = 9.1 y = 9.1/3 = 3.0333... or 91/30 or 3 1/30.
What is the common point of these equations 2x plus 3y equals 12 and x - 3y equals -3?
(3, 2) because x = 3 and y = 2
What type of lines are these x-3y equals -3 and 6x plus 2y equals -12?
perpendicular
What is the slope of 3x plus 3y equals 12?
The slope is -1. 3x+3y=12 Subtract 3x 3y=-3x+12 Divide by 3 y=-x+4
X - 3y equals -3 and 6x plus 2y equals -12?
x = 3y - 3 so 6 (3y - 3) + 2y = -12 ie 18y - 18 + 2y = -12 ie 20y = 6 so y = 0.3 and x = -2.1
What is the solution of 3x plus 2y equals 13 and 2x plus 3y equals 12?
x = 3 and y = 2
Can anyone help solve this problem 7y plus 2 equals 3y-10?
7y = 3y - 12 4y = -12 y = -3
Graph -8x plus 3Y equals 12?
-8x+3y=12 3y = 8x+12 y = (8/3)x + 4 So it will be a line with slope 8/3 and y intercept of 4
What is the common point of these equations 2x plus 3y equals 12 x-3y equals -3?
x = 3 and y = 2 so the lines intersect at the point (3, 2)
How do you solve 7x plus 3y equals 30 -2x plus 3y equals 3 in an order pair?
(3,3)
-3 plus 3y equals 2y plus 5?
3y - 3 = 2y + 5 3y - 2y = 5 + 3 y = 8
