4x-7=5x-2 x=-5
3x+2 = 5x so 2x = 2 and hence x = 2/2 = 1
5x-2y=11 -2y=-5x+11 y=(5/2)x - 11/2 Slope is 5/2
5x-3 = 11+12x 5x-12x = 11+3 -7x = 14 x = -2
Y=-1/2(x)
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.

This cannot be solved. It needs 2 equations to solve for 2 unknowns.
-10.
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.
