Solve
5x + 2 − 2(x − 1) = 3x + 4
5x + 2 - 2x + 2 = 3x + 4
3x + 4 = 3x + 4
4 = 4

For which values of A, B, and C
will Ax + By = C be a vertical line
through the point (9, 3)?
The equation for a vertical line through (9,3) is x = 9.
Thus,
A=1, b=0 and c=9

Solve the system of equations using substitution:
4x + 3y = -8
y = 8x – 12
Plug in 8x - 12 for y
4x + 3(8x - 12) = -8
4x + 24x - 36 = -8
28x = 28
x = 1 (then plug in to find y)
x = 1 and y = -4

Solve by factoring (or quadratic formula)
7x^2+16x=-4
First, add 4 on both sides to get a zero.
Then, either AC method or guess & check to factor.
AC= 28 (so factors of 28 that add to 16: 14&2)
7x^2+14x+2x+4
Then group and factor the GCF
7x(x+2)+2(x+2)
Then factor out the (x+2)
(x+2)(7x+2)=0
Thus, x = -2 or -2/7
