3x plus 7y equals 37 and x equals 3 then y equals?
4
Factor 21-7y plus 3x-xy?
21-7y+3x-xy7(3-y)+x(3-y)
What is 5x plus 3 equals 18?
5x + 3 = 18 Subtract 3 from both sides: 5x = 15 Divide by 5: x = 3.
How do you factorise 2xy - 6x plus 7y -21?
2x(y - 3) + 7(y - 3) = (2x + 7)(y - 3)
What is the y-intercept of 7y 3x-21 equals 0?
y-intercept = 3y-intercept ; x = 07y + 3x - 21 = 07y + 3(0) -21 = 07y -21 = 07y = 217y/7 = 21/7y=3
What is the answer to 7y plus 18 equals 39?
7y + 18 = 39 Therefore, 7y = 39 - 18 = 21 y = 21/7 y = 3
What is 39-7y equals 18 equal?
39 - 7y = 18,-7y = 18 - 39-7y = -21-7y/-7 = -21/-7y = 3
-6y plus 3 equals -7y plus 8?
-6y+3 = -7y+8 -6y+7y = 8-3 y = 5
What is 3x plus 7y if x equals 6 y equals 4?
3x + 7y = 3*x + 7*y = 3*6 + 7*4 = 18 + 28 = 46
How do you solve 4y plus 3 equals 7y-18?
4y + 3 = 7y - 18Add 18 to each side of the equation:4y + 21 = 7ySubtract 4y from each side:21 = 3yDivide each side by 3:7 = y
3x plus 7y equals 37 and x equals 3 then y equals?

How do you rewrite this equation so that y is a function of x 1 plus 7y equals 5x-2?
1 + 7y = 5x - 2 7y = 5x - 3 - 5x = - 7y - 3 x = 7/5y + 3/5 ---------------------
What is th y intercept of 7y plus 3x-21 equals 0?

What is the y-intercept in this linear equation 7y plus 3x - 21 equals 0?
7y+3x-21 =0 7y = -3x+21 y = -3/7x+3 The y intercept is 3
What is 3x plus 7y equals -16 -x-y equals 4?
y = -1 and x = -3
Can anyone help solve this problem 7y plus 2 equals 3y-10?
7y = 3y - 12 4y = -12 y = -3
What is the ordered pair of 4x-7y equals -23 8x plus 5y equals 49?
The lines intersect at (3, 5)
