4x + 3y = 5...(1)
2x + 3y = 1...(2)
(2)*2:
4x+6y=2...(3)
(1)-(3):
4x+3y-(4x+6y)=5-2
4x+3y-4x-6y=3
-3y=3
y=-1
By sub. y=-1 in (2), we have
2x+3(-1)=1
2x-3=1
2x=4
x=2
The solution is x=2,y=-1
It is -11x + 24 because you multiply the numbers in the parentheses by 3 then collect like terms 10x +24 - 21x then you do 10x minus 24x and you get -11x+24
D.
None of the above. Because your expression would be, 2 + 0.75 x 6.
Hope it helps. ;)
Answer:
Given expression is,
9(x+3) = 108
In solving the equation the steps are as follows,
Step 1 : 9x + 27 = 108 ( By distributive property )
Step 2 : 9x = 81 ( Subtracting 108 on both sides )
Step 3 : x = 9 ( Divide both sides by 9)
Hence, by the above explanation we can drag the steps of solution in correct order.
