What else can I help you with?
Where do the parentheses go in 6y plus 2-2y equals 6y if y equals 5?
6y + (2-2)y = 6y 6(5) + (2-2)5 = 6(5) 30 + 0 = 30
What does 4x plus 6y equals 24 7x plus 6y equals 9?
It does nothing! 4x + 6y = 24 7x + 6y = 9 Subtracting the first equation from the second gives: 3x = - 15 so that x = -5 Substituting the value of x in the first equation gives -20 + 6y = 24 so that 6y = 44 and so y = 22/3 or 71/3
4x plus 6y equals 62 -6x plus 6y equals -18?
Subtracting gives: 10x = 80 so x = 8 and y = 5
X equals 5 and y equals 6 then what is 9x plus 6y?

6y-5 equals 8 plus 10y?
6y-5=8+10y 6y-10y=8+5 -4y=13 y=-3.,25 because: 6*3.25-5=-24,5 and 8+10*3.25=-24,5 true
-6y plus 3 equals -7y plus 8?
-6y+3 = -7y+8 -6y+7y = 8-3 y = 5
-6y plus 5 equals -67?
-6y + 5 = -67y=12-6y = -72-y = -12y = 12
6y plus 5 equals 11y plus 30?
6y+5 = 11y+30 -25 = 5y -5 = y
Where do the parentheses go in 6y plus 2-2y equals 6y if y equals 5?
6y + (2-2)y = 6y 6(5) + (2-2)5 = 6(5) 30 + 0 = 30
Solve the equation10y equals 6y plus 5 plus 3y?
10y= 6y+5+3y 10y=6+9y y=6
What does 4x plus 6y equals 24 7x plus 6y equals 9?
It does nothing! 4x + 6y = 24 7x + 6y = 9 Subtracting the first equation from the second gives: 3x = - 15 so that x = -5 Substituting the value of x in the first equation gives -20 + 6y = 24 so that 6y = 44 and so y = 22/3 or 71/3
4x plus 6y equals 62 -6x plus 6y equals -18?
Subtracting gives: 10x = 80 so x = 8 and y = 5
X equals 5 and y equals 6 then what is 9x plus 6y?

6y-5 equals 8 plus 10y?
6y-5=8+10y 6y-10y=8+5 -4y=13 y=-3.,25 because: 6*3.25-5=-24,5 and 8+10*3.25=-24,5 true
Are 3x-4y equals -5 and 8x plus 6y equals -5 parallel or perpendicular lines?
They are perpendicular lines because the slopes are 3/4 and -4/3 respectively.
In 2x plus 6y equals 32 what is x?
2x plus 6y equals 32 32 divided by 6= 5 R2 5+2= 7x6= 42-5=37-2=35 so X=5
What is 10X plus 6Y equals 100 if 6X plus 10Y equals 92?
X=7 y=5
