y=7+x =x=7-x
-6
x-y = 6 -x-3y = 22 -4y = 28 y = -7 So by substituting: x = -1 and y = -7
no you smell
y=x+7 x - intercept set y to 0 0=x+7 -7 -7 -7=x (-7,0) y - intercept set x to 0 y=0+7 y=7 (0,7) (-7,0) , (0,7)
y=7+x =x=7-x
x = -2
Y = x - 7
x = -3, y = 7
x = 11/7 and y = 12/7
Can you help with this equation? Thanks. Solve for x and y and z for the following. x plus y plus z equals 9 x plus 2y plus 3z equals 23 x plus 5y plus -3z equals -7
y=(7-x)/4
x = -2 and y = 3
the answer is 7
x = 5, y = -2
10
If: x = 7 Then: y = (2*7)+3 = 17 And: 5x+y = (5*7)+17 = 52
