7x = 5+5x 7x-5x = 5 2x = 5 x = 2.5
x=6
The Y intercept of y=7x+10 is 10.
7x + y + 3 = y7x + 3 = 07x = -3x = -3/7
7x = 3 x = 3/7
x=3 actually its 7
The measure of 7x + 27 depends on the value of x.
x = 3
+ 27 =
-46 = 3x + 7x
7x + y = 8 Subtract 7x from each side of the equation: y = -7x + 8
So 17 = 9x, making x = 1 and 8/9
7x+3y where x=2 and y=9 can be written as (7*2)+(3*9) which can be simplified to (14)+(27), from there it's basic addition.
13x
It is 9x
x=6
-7x + 5 = -9 -7x = -14 7x = 14 x = 2
