4x + y = 9
so that y = 9 - 4x
7x - 8y = 6
7x - 8*(9-4x) = 6
7x - 72 + 32x = 6
39x = 78
x = 2
Then y = 9 - 4x = 9-4*2 = 9-8 = 1

If-4x plus 6 equals 38 what do x equals?
if -4x+6=38 what x=
-10x-6 plus 4x equals -4x plus 8?
-6x-6 -or- -6(x+1)
How tosolve 4x plus 2 plus 6 equals 2?
4x + 2 + 6 = 2 4x + 8 = 2 4x = -6 x = -6/4 = -3/2
4x plus 32 equals -4x plus 16 x equals?
4x+32=-4x+16x4x+32=12x-4x -4x32=8x/8 /84=x
4x plus y-6 equals 0?
Then the straight line equation is: y = -4x+6
If-4x plus 6 equals 38 what do x equals?
if -4x+6=38 what x=
-10x-6 plus 4x equals -4x plus 8?
-6x-6 -or- -6(x+1)
How tosolve 4x plus 2 plus 6 equals 2?
4x + 2 + 6 = 2 4x + 8 = 2 4x = -6 x = -6/4 = -3/2
4x plus 32 equals -4x plus 16 x equals?
4x+32=-4x+16x4x+32=12x-4x -4x32=8x/8 /84=x
4x plus y-6 equals 0?
Then the straight line equation is: y = -4x+6
6x plus 4 equals x plus 12 plus 4x-6?
6x+4 = x+12+4x-6 6x-x-4x = 12-6-4 x = 2
3x plus 4x plus 6 equals 41?
x=5
If x equals 8 then 4x plus 6 equals 46?
No. Substitute the value 8 for x, and you have 4x +6 = 4(8) +6 = 32 +6 = 38.
What is the ordered pair for 2y equals 4x plus 8 and 4y equals 4x plus 20?
x = 1 and y = 6 so the lines intersect at the point (1, 6)
What is 6 -2x plus 8 plus 4x equals 8?
x=5
2x plus y equals 3 2y-6 equals -4x?
4x + 2y = 6 (first equation x 2) 4x + 2y = 6 (second equation rearranged) No unique answer exists
What is the slope of 4x plus 3y equals 6?
4x+3y = 6 3y = -4x+6 y = -4/3x+2 in slope intercept form
