< that I think maybe be the answer hope that's help
2x + y = 1 . . . . . (1)
4x + 2y = -2 . . . .(2)
From (1), y = 1 - 2x . . . . . (3)
Putting (3) into (2) gives:
4x + 2(1 - 2x) = -2
4x + 2 - 4x = -2
2 = -2
Therefore, there is no x value as there is no solution for the set of equation.
X = y
y = 4
By the substitution property, we can replace y with 4 in that first equation.
x = 4
Your answer is: 20
They have 4 different backgrounds and 5 different poses which means you just have to multiply the 4 backgrounds*the 5 different poses to discover how many different pictures you could have at the most.
hope this helps!
