5x + 2 = 22 5x = 22 - 2 5x = 20 5x/5 = 20/5 x=4
5x=10 5x/5=10/5 x=2
The question contains two equations:5x - 6y = 15 5x + y = 2 There are no inequalities in the question.

5x2+500 = 844.45 5x2 = 844.45-500 5x2 = 344.45 x2 = 344.45/5 x2 = 68.89 x = the square root of 68.89 = 8.3 x = 8.3
4x-7=5x-2 x=-5
5x-5 = -3 5x = -3+5 5x = 2 x = 2/5
Here is the work for that problem: 5x+ 2=12 5x= 12-2 5x=10 x= 2
f(x)=5x+2
5x + 2 = 22 5x = 22 - 2 5x = 20 5x/5 = 20/5 x=4
5x=10 5x/5=10/5 x=2
The question contains two equations:5x - 6y = 15 5x + y = 2 There are no inequalities in the question.
