Answer: A) x + 4x = 35; 7 large stones and 28 small stones
======================================================
Explanation:
x = number of large stones
4x = number of small stones
x+4x = total number of stones = 35
x+4x = 35 is the equation to solve
-----------
Let's isolate x
x+4x = 35
5x = 35
x = 35/5
x = 7 large stones are needed
4x = 4*7 = 28 small stones are needed
(3x+7)+26=90
3x+33=90
3x=90-33
3x=57
X=19 is the value of x shown below
You just subtract. The standard form of a complex number is a+bi
1 - 4 = -3
-i - (-5i) = 4i
The answer is -3 + 4i
