Answer:
The consultant sold 15 circular stones and 22 rectangular ones
Step-by-step explanation:
let quantity of circular stones be X , rectangular ones be Y
thus:,We can deduce that,
26x+34y=1138...... equation 1
He sold total of 37 ,both stones
x+y=37... equation 2
Solving simultaneously
make Y subject of the formula in equation 1
34y=1138-26x
Answer:
Step-by-step explanation:
Conditions
Let the circular stones = x
Let the rectangular stones = y
Equations
x + y = 37 Subtract x from both sides of this equation.
y = 37 - x Notice that x is on the right side of the equation
Solution
26x + 34y = 1138 Substitute for y
26x + 34(37 - x) = 1138 Remove the brackets
26x + 1258 -34x= 1138 Combine
-8x + 1258 = 1138 Subtract 1258 from both sides
-8x +1258-1258 = 1138-1258 Combine.
-8x = -120 Divide both sides by -8
-8x/-8 = -120/-8
x = 15 Two minuses make a plus (last step)
x+ y = 37
15 + y = 37 Subtract 15 from both sides
15-15 +y = 37-15 Combine
y = 22
Answer
x = 15 Circular pizza dishes
y = 22 square pizza dishes
