3(x-1) = 2x - y
3x-3 = 2x-y
3x-2x+y = 3
x + y = 3 ----> (1)
2(x+y) = 3+3y
2x + 2y = 3 + 3y
2x + 2y - 3y = 3
2x - y = 3 -----> (2)
make equation (1) and (2) together
x + y + 2x - y = 3+3
3x = 6
x = 2
now make x = 2 in equation (1)
x + y = 3
2 + y = 3
y = 3-2
y = 1
(x,y) = (2,1)
Answer:
100
Step-by-step explanation:
add all the number together 3 + 4 + 2 +1=10
250/10=25
then times 25 with the 4 number at the top
25 times 4 =100
so there is 100 blue pencils
Answer: 3
Step-by-step explanation: 6 is 3 and 3 so b is 3 and x is 3
