the answer is 7
If: x = 7 Then: y = (2*7)+3 = 17 And: 5x+y = (5*7)+17 = 52
(3, 1)
Well what does y equal? If y equals 7 the 3+7=10
x = -3, y = 7
3 + Y where Y = 7 Substitute 7 for Y (because Y = 7) so: 3 + 7 = 10.
7x + y + 3 = y7x + 3 = 07x = -3x = -3/7
x = 5, y = -2
10
9 plus 7 equals 144. Generally, x plus y = x(x+y).
x = 3 and y = 5
It equals a simple linear equation in 'y'. Its solution is 7/3 .
-6
y intercept 7 x intercept 7/3
4y + 7 = 19 ∴ 4y = 12 ∴ y = 3
The intercept is [ y = 7 ] .
y= -25
