7x y5 is not an equation, inequality nor even an expression.
In any case, the "equation" appears to resemble a linear equation. If that is the case, it cannot be solved because you need two independent linear equations to solve for two variables.
7x + 2 = 5,6
Subtract by 7x and divide by 2.
7x+2-2=16-27x = 147x/7 = 14/7x = 2
Assume you mean -7x-2=0 solve for x -7x-2=0 -7x=2 -x=2/7 X=-2/7
2y + 7x + y-1?
4x-y2=2xy 2x ? y5 if its plus its 7 xy
-7x + 6 + 7x - 2 = 4
7x + y = 4y = 4 - 7x
40 -7x = -16 -7x = -16 -40 -7x = -56 x = 8
x2+7x+12
7x-3=39 7x=42 x=6
7x + 2 = 5,6
Subtract by 7x and divide by 2.
y5(x3 - 8)
7x+2-2=16-27x = 147x/7 = 14/7x = 2
Assume you mean -7x-2=0 solve for x -7x-2=0 -7x=2 -x=2/7 X=-2/7
7x=42 x=42/7 or, x=6
