-8x -7y
3y + 18 = -8x + 3Subtract 18 from each side:3y = -8x - 15Divide each side by 3:y = (-8/3)x - 5
(1, 1)
7x+3y=-52 3(8x-y=-74) 7x+3y=-52 24x-3y=-222 7x=-52 + 24x=-222 31x=-274 x=8.8387
x+7x+3y-y =8x+2y =2(4x+y)
8x + 3y = 248x - 8x + 3y = -8x + 243y = - 8x + 243y/3 = (- 8x + 24)/3y = -8x/3 + 24/3y = (-8/3)x + 8 this is the slope-intercept form of the equation of the line, y = mx + b, where the slope m is -8/3 and the y-intercept b is 8.
4x + 3y = 8x + y so 3y - y = 8x - 4x ie 2y = 4x so y = 2x
-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
-8x -7y
Oh, dude, you just gotta rearrange that equation to make it look all fancy. So, the standard form for 8x - 3y = 6 - 4x would be 12x + 3y = 6. It's like putting on a nice suit for a math party, you know?
3y + 18 = -8x + 3Subtract 18 from each side:3y = -8x - 15Divide each side by 3:y = (-8/3)x - 5

16x2 + 8x + 1 - 9y2 = (4x + 1)2 - (3y)2 which is a difference of two squares. = (4x + 1 + 3y)*(4x + 1 - 3y)
7x+3y=-52 3(8x-y=-74) 7x+3y=-52 24x-3y=-222 7x=-52 + 24x=-222 31x=-274 x=8.8387
10x - 5y + 2x - 3y = 12x - 8y

The answer would be Y=8/3x + 5/-3 This is how to do it: First, you have to isolate 'Y' in the equation. You do this by adding the opposite of all terms, not 'Y' though, to both sides of the equation (but first you have to make sure ALL like terms are added(none here), and you have to tik-tok(convert all subtraction to adding negatives instead(Example x-3 --->x+ -3)(none here)) : 8x - 3y - 5=0 ----> 8x + -3y + -5=0 ---> (8x + -8x) + -3y + (-5 + 5) = 0+ -8x + 5 ---> -3y= 0+ -8x + 5 Now you divide all terms by the coefficient of y, here being -3. DON'T FORGET IF IT'S POSITIVE OR NEGATIVE!!!!!! Like here: -3y/-3 = -8x/-3 + 5/-3 -----> Y= 8/3 x + 5/-3 Hope I helped :-)
