x - 5 = 2, we can solve for x by adding 5 to both sides yielding: x = 7
x+3y=2 x= -5 y = 1
2
(x - 3)(x + 5)
X+3=5 Is the same as 2+3=5. One way to look at it is to subtract the number from te answer. So, 3-5 equals 2. 2=X.

You fill in for x and solve the equation3(5)^2 - 2(5)15^2 - 10; now solve
x - 5 = 2, we can solve for x by adding 5 to both sides yielding: x = 7
x+3y=2 x= -5 y = 1
2
(x - 3)(x + 5)
X+3=5 Is the same as 2+3=5. One way to look at it is to subtract the number from te answer. So, 3-5 equals 2. 2=X.
Subtract two from both sides and you are left with X equals -5
x = 5, y = -1

x equals 4 over 35
(x + 7)2 = 5 x + 7 = ±√5 x + 7 - 7 = -7 ± √5 x = -7 ± √5
