( (45) (9x) )
9x = 4x + 45 5x = 45x = 9
9x-3y=63 7x-3y=45 -3y=63-9x -y=21-3x y=-21+3x 7x-3(-21+3x)=45 7x+63+9x=45 7x+9x=45-63 16x=-18 x=-1.125 y=-21+3(-1.125) y=-24.375 (-1.125,-24.375)
To solve the expression ( 14 + 3(3x + 3)(x - 5) ), first simplify the term ( 3(3x + 3) ) by distributing the 3, giving ( 9x + 9 ). Next, multiply this result by ( (x - 5) ) using the distributive property: ( (9x + 9)(x - 5) = 9x^2 - 45x + 9x - 45 = 9x^2 - 36x - 45 ). Finally, combine this with the 14 to get ( 9x^2 - 36x - 45 + 14 = 9x^2 - 36x - 31 ).
9x
5x+4x-10 = 35 9x = 35+10 9x = 45 x = 5
9x = 4x + 45 5x = 45x = 9
9x+6=51 9x = 45 x= 5 9x-6=51 9x = 57 x= 6.33
9x-3y=63 7x-3y=45 -3y=63-9x -y=21-3x y=-21+3x 7x-3(-21+3x)=45 7x+63+9x=45 7x+9x=45-63 16x=-18 x=-1.125 y=-21+3(-1.125) y=-24.375 (-1.125,-24.375)
9x23
If: 12 = 9x+3 Then: 12-3 = 9x And: 9 = 9x So: x =1
Add 45 to each side, giving 9x = 45. Divide both sides by 9, giving x = 5
5/x4
9x - 9 = 36 9x = 45 x = 5
It is equal to -18x^2 +9x
In one bracket, write 16 times the square root of 2 minus 3x. In the other one, write 16 times the square root of 2 plus 3x.
