Add: 5x - y + x + y + 8 + 10 ie 6x = 18 so x = 3 and y = 7
If: y = 8x+7 then the y intercept is 7 and the slope is 8
8+y = 7+5y y-5y = 7-8 -4y = -1 y = 1/4
3 + Y where Y = 7 Substitute 7 for Y (because Y = 7) so: 3 + 7 = 10.
Y=5
4y + 10 = -18 4y = -28 y = -7
It is an equation and the value of y is 18
18 + 70 ie 87
7y + 18 = 39 Therefore, 7y = 39 - 18 = 21 y = 21/7 y = 3
How do you add 2x plus 3y equals 18 in 5x-y equals 11
Y+7=9 equals 2+7=9.
the answer is 7
(3,21)
3x + 7y = 3*x + 7*y = 3*6 + 7*4 = 18 + 28 = 46
(3, 1)
Add: 5x - y + x + y + 8 + 10 ie 6x = 18 so x = 3 and y = 7
The intercept is [ y = 7 ] .
