Answer:
around 3
Step-by-step explanation:
A solution to an equation is a number that can be plugged in for the variable to make a true number statement. Example 1: Substituting 2 for x in. 3x+5=11. gives.
The answer is D.
6x * 6x = 36x^2
6x * -7 = -42x
6x * 7 = 42x
-7 * 7 = -49
The -42x and 42x cancel each other out, resulting in 36x^2 - 49.
x - y = 30
x - 15 = 30
+ 15 + 15
x = 45
(x, y) = (45, 15)
