5x+2=x+10 5x-x=10-2 4x=8 x=2
5x+10=40 5x+10-10=40-10 5x=30 5x/5=30/5 x=6
4x - 10 + 5x = 719x = 81x = 9
5x+2=2x-10 x=-4
5x+10=60 5x=50 5/5=1 50/5=10 So the answer is 10
5x+25=10 5x+25-25=10-25 5x=-15 5x/5=-15/5 x=-3
x=-10
4x + 55 = 9x + 10 55 = 5x + 10 45 = 5x x = 9
If 5x plus 3y equals 13, the x equals 2 and y equals 1. This is because 5x2=10 and 3x1=3, and 10+3=13.
x = 10x, so derivative = 10
5x - 4x = 13 - 3 ie x = 10
5x + 20 = 4x +30 5x - 4x = 30 - 20 x = 10
