To get ride of the complex fraction, you need to do multiply 7/4 by the reciprocal of 9/10, like so:

7/4 * 10/9 = 70/36

To simplify divide by 2, the answer is

Consider the following pair of equations:

Aloiza [94]

Y = 3x + 3 this is equation 1
y = x -1 this is equation 2
since equation 1 and 2 already defined y in terms of x, we're just gonna substitute y into the other equation. as 2 is shorter I'm going with that today
x - 1 = 3x +3
-1 - 3 = 3x - x
-4 = 2x
x = -2
now we've got x just sub it in equation 2
y = -2 -1
y = -3
so the answer is (-2,-3)
