The word in the problem that indicates is a negative number is “descend”
The area of a Square is 144 because 12x12 is 144 and if both sides are 12 then that equals 144.
Hope this helps!
Equation 1) 10x + 2y = 30
Equation 2) 4x + y = 4
Multiply all of equation 2 by 2.
2) 2(4x + y = 4)
2) 8x + 2y = 8
1) 10x + 2y = 30
Subtract equations from each other.
-2x = -22
Divide both sides by -2.
x = -22/-2
x = 11
B) x = 11
~Hope I helped!~
Maybe step 3 because you try to get rid of the x on both sides
Write this as an equation and solve
The number is 30
