-3/5
x=4/3
It is 3 and the slope is 3/5
3x+7=15 -7 -7 3x=6 (Divide) 3 3 x=2 Check it: 3(2)+7=15 6+7=15 15=15 :D
5X + 6 = 2X + 15 -2X -2X 3X + 6 = 15 -6 -6 3X = 15 ---- ----- 3 3 x = 5 im so smart.
3x = 6x - 15Add 15 to each side:3x + 15 = 6xSubtract 3x from each side:15 = 3xDivide each side by 3:5 = xAdd 8 to each side:13 = x + 8
3x + 1 = -14 -1 -1 ___________ 3x = -15 divide both sides by 3: x = -5
x = 0
x = 15 as 4*15+6 = 66 3*15+21 = 66 or an easier way to do it 4x - 3x = 1x 21 - 6 = 15 1x = 15
Get in slope intercept form. 3X + 5Y = 15 5Y = -3X + 15 Y = -3/5X + 3 -3/5 is the slope of this line and the line parallel to this line
15=30-3x 15-30=3x -15=3x -15/3=x -5=x
-3x=-15+6 -3x=-9 x=-9/-3 x=3
