4x+35-2x+25 = 6 2x+60 = 6 2x = 6-60 2x = -54 x = -27
5
=> 2x + 5x = 35{collect x's}=> 7x = 35{divide both sides by 7}=> x = 35/7 = 5
2x + 5x = 357x = 35x = 35/7x = 5
-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
