If: x = -5
Then: y = (3*-5)-1 = -16
If: 5-3x = x+1 then the value of x = 1
2x+5=3x+1 -x=-4 x=4
3x-5=3x+5 There is no solution.
3x + 1 = -14 -1 -1 ___________ 3x = -15 divide both sides by 3: x = -5
5*2-3x-1 = 0 10-3x-1 = 0 -3x = 1-10 -3x = -9 x = 3
If: 3x+5 = 4x+1 Then: x = 4
y = mx + b y-5 = 3x-1 y-5+5 = 3x-1+5 y = 3x + 4
5=3x+2 3x+2-2=5-2 3x=3 ------ 3 x=1
3x+5=2, 3x=2-5 (sign changes) 3x=-3 x=-1
If: 5-3x = x+1 then the value of x = 1
2x+5=3x+1 -x=-4 x=4
3x-5=3x+5 There is no solution.
3x + 1 = -14 -1 -1 ___________ 3x = -15 divide both sides by 3: x = -5
- 7/5
3x + 2 + 2x = 7; 3x + 2x = 5x, so 5x + 2 = 7; 7-2=5, so 5x=5. 5x divided by 5 and 5 divided by 5 equals 1, so x equals 1.
3x - y = -1 x = -2 3(-2) -y = -1 -6 - y = -1 -y = 5 y = -5
5*2-3x-1 = 0 10-3x-1 = 0 -3x = 1-10 -3x = -9 x = 3
