5x + 4 = 10x - 5 10x - 5x = 4 + 5 5x = 9 x = 1.8
10x + 13 = 1710x = 17-1310x = 4x = 4/10x = 0.4
x = 4
If: 4y+10x = 16Then: 4y = -10x+16And: y = -2.5x+4
6-3x = 5x-10x+2 4 = 8x-10x 4 = -2x x = -2
5x + 4 = 10x - 5 10x - 5x = 4 + 5 5x = 9 x = 1.8
y=-10x-4
10x + 13 = 1710x = 17-1310x = 4x = 4/10x = 0.4
x = 4
If: 4y+10x = 16Then: 4y = -10x+16And: y = -2.5x+4
6-3x = 5x-10x+2 4 = 8x-10x 4 = -2x x = -2
2x + (10x - 4) = 20 2x + 10x - 4 = 20 12x - 4 = 20 12x = 24 x = 2
7x = 3 x = 3/7
10x + 13 = 17 ie 10x = 17 - 13 so x = 4/10 = 0.4
3x-13x+4=0 -10x+4=0 4=10x 4/10=x simplified: x= 2/5
-4 = 17x so x = -4/17
12x - 6 = 10x +2 12x - 10x = 2 + 6 2x = 8 x = 4
