" -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.
a + 7y
no its not a solution
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
x = 7y x/7 = y
-5x+7y-6z
It is: 8+7y
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.
Solving equations in two unknowns requires two independent equations. Since you have only one equation there is no solution.
