Answer:
x= -2 and y= 8
Step-by-step explanation:
8x+5y=24-------A
y=-4x---------B
Putting the value of y from B in A
8x+5(-4x)=24
8x +(-20x)= 24
8x-20x=24
-12x=24
x= -24/12
x=-2--------C y =-4(-2)=8
what type of math is this I might be able to help
Composite number is made up of 2 or more prime numbers
a prime number is only made up of itself and 1
composite and prime numbers are like oposites
a prime is not a composite but it is a prime number
confusing quesiton
X+15 = 3x - 7 => 22 = 2x => x=11
First, you need to collect the like terms; 7x + (-20 - 90). Next simplify; 7x - 110
answer; 7x - 110
