Answer:
-9
Step-by-step explanation:
Substitute the give values into the correct place in the equation.
Since x=2, y=3,
Place "2" in the x of the equation, and "3" into the y of the equation.
x²-5y+2
= 2² - 5(3) + 2
= 4 - 15 + 2
= -9

Answer:
7
Step-by-step explanation:
first, we would set up an equation. let 3x-4 represent "four less than a number tripled". "a number" would be represented by x. let x+10 represent "the same number increased by 10".
set 3x-4 and x+10 equal to each other:
3x-4=x+10
next, we would solve this equation for x. first we would get the x together on one side of the equation. we would do this by subtracting x from both sides to remove it from the right side of the equation:
2x-4=10
then, we would get the 2x by itself. we would do this by adding 4 to both sides:
2x=14
finally, we would divide each side of the equation by 2 to find x:
x=7.
The number is 7.
