<span>y= 1.5x - 4
y= -x
replace </span>y= -x into y= 1.5x - 4
y= 1.5x - 4
-x = 1.5x - 4
1.5x +x = 4
2.5x = 4
x = 1.6
y= -x
y = -1.6
answer: (1.6, -1.6) is the solution
You put in the number for x. Here are the answers across
6 6 6
18 9 18
30 12 30
Let n = the unknown number.
The phrase "five is" tells us to start the equation with "5 ="
"Seven more than" becomes "7 +"
"The product of two and a number" is 2n or (2 * n)
Put it all together and solve:
5 = 7 + 2n
5 = 7 + 2n
5 - 7 = 2n
- 2 = 2n
Divide each side by 2 to isolate the variable
- 1 = n
Your number is - 1
