2y+3y-7y+4=16 -2y=12
y=-6
Check it
-12-18+42+4=16
-30+46=16
16=16
The equation is -2y + 16 = 10
x = 8 and y = 0
x+2y = -1 and 5x-4y = 16 Solving the simultaneous equations gives: x = 2 and y = -1.5
This means that 2y - 3 = 2y + 4 which is not possible.
y=16 x= -4
Without an equality sign and not knowing the plus or minus values of 7y and 2y the expression given can't be considered to be an equation
The equation is -2y + 16 = 10
Subtract first from second gives -4x = 16 so x = -4 and y = -7
the slope of the line is -4
x = 8 and y = 0
x+2y = -1 and 5x-4y = 16 Solving the simultaneous equations gives: x = 2 and y = -1.5
This means that 2y - 3 = 2y + 4 which is not possible.
y=16 x= -4
No 2y-3 is not equals y plus 2AND how old are u?
(3, 2)
2y+26 = 28 2y = 28-26 2y = 2 y = 1
-2y=x+8 is the answer
