If: 9y-20y = 25 Then: y = -25/11
It can be simplified to: 9y-2x
-7x+9y = 54 9y = 7x+54 y = 7/9x+6 which is now in slope-intercept form
7x - 9y = -63.When y = 0 then the resultant answer provides the x intercept.7x - 0 = -63 : x = -9When x = 0 then the resultant answer provides the y intercept.0 - 9y = -63 : y = 7Alternatively, to ascertain the y intercept convert the equation into the form y = mx + c, c is the y intercept.7x - 9y = -63 : -9y = -7x -63 : 9y = 7x + 63 : y = 7/9x + 7
9y - 4x
2x=7x=9x
7x = 18 - 2x 7x + 2x = 18 9x = 18 x = 2
(7x)(2x - 27) This means multiply the '7x' to each term in the other set of brackets. Hence 14x^2 - 189x
8x + 20y
4y + 3w + 4x + 9y + 7x - 7w (combine like terms)-4w + 11x + 13y
-2x+9y=-35 add 2x to both sides to get 9y=2x-35 divide both sides by 9 to get y=2/9 x - 35/9 the Y intercept is 0, ~-3.889 and the slope is 2/9
To simplify the expression 2x + 3y + 4x + 9y, you first combine like terms. Adding the coefficients of x terms gives 2x + 4x = 6x. Similarly, adding the coefficients of y terms gives 3y + 9y = 12y. Therefore, the simplified expression is 6x + 12y.
