" -7y plus 1975 " is not an equation, it doesn't ask any question, and it needs
no solution.
It's just an expression that stands for a number. There's no way to know what number
it stands for until you know what number 'y' is.
no its not a solution
a + 7y
If the equations are 8x + 7y = 37, and 2y = 4x -2 then the answer is yes.
16+7y-8 = 7y+16-8 = 7y+8
-7y + 4y = -3y
-6y+3 = -7y+8 -6y+7y = 8-3 y = 5
7y + 4 - 4 - 9 = 7y - 9
There is no solution. Your system looks like this:x + 7y = 2x = 9 - 7yThe first can be rewritten as x = 2 - 7y,and then join the two as 9 - 7y = 2 - 7yAdding 7y to both yields 9 = 2 which is false, so there's no solution.You can convert these to slope/intercept form as:y = -x/7 + 2/7y = -x/7 + 9/7These are parallel lines, and will never intersect, so there is no solution that satisfies both equations.
x = 7y x/7 = y
-5x+7y-6z
It is: 8+7y
Solving equations in two unknowns requires two independent equations. Since you have only one equation there is no solution.
