Answer:
x = 0
Step-by-step explanation:
if 2y + x = 4
we can assume that y = 2
if y - 3x = 2
it means 2 - 0 = 2
therefore x = 0
1 out of 52. So 1/52 equals some decimal. Plug in calc.
21 + 15 = 36
36 x 3 = 108
Their father donated $108 to charity
Solve for y by simplifying both sides of the equation, then isolating the variable.
y = x^2/2^z - w/2z
