Answer: x = 11
Step-by-step explanation:
You didn't state what you needed for these problems so I'm going to assume you need to solve for X.
1st Equation:
3x - y = 23 --> y = 3x - 23
2nd Equation:
2x + 3y = 8 --> (3y = 8 - 2x)/3 = y = 8/3 - 2x/3
Set Equations = to Each other
3x - 23 = 8/3 - 2x/3 --> 3x - 2x/3 = 8/3 + 23
9x/3 - 2x/3 = 8/3 + 69/3 --> 7x/3 =77/3
7x/3 X 3/7 = 77/3 X 3/7
x = 11
If you need to solve for y as well plug the x value back into the original equation and solve.
I hope this helps you
2x=17+3
2x=20
x=10
Answer:
pretty sure x=0 if not it might be infinite solutions but im pretty sure its just 0.
I plugged it in and i think it works

Answer:
A
Step-by-step explanation:
Area of rectangle = length x width
length = 5x - 2
width = x
area = (5x - 2) × x
100 = 5x² - 2x
the width would be less than the area of the rectangle, thus the inequality sign to be used is <
5x² - 2x < 100
Answer:
Step-by-step explanation:
(-6,-5) , ( 0,-1) , (-3 , -3) , (2 , 0 ) are solution of the inequalities.
The point that lies on the purple area and on the solid line are the solutions of the equations.
