What is three equals two times x plus five?
3 = 2x + 5 -5 -5 -2 = 2x ---------- 2 x = -1
2X plus 2 equals X plus 5?
2x+2=x+5 x=3
Factorise 2x plus 7 plus 5?
2x + 7 + 5 = 2x + 12 = 2*x + 2*6 = 2*(x+6)
What is the answer to 2x plus 4 times 4x plus 5?
18x + 5
What is the solution of 2x plus 3 equals 3x plus 5?
2x+3 = 3x+5 2x-3x = 5-3 -x = 2 x = -2

What is the answer 2 x plus 1 plus 5?
That's not real clear. It could be 2 times positive 1 (which is 2) plus 5, which equals 7. It could be 2x + 1 + 5 which equals 2x + 6 It could be 2x + 1 = 5, in which case x = 2
What is the vertical asymptote of X minus 7 divided by negative 2X plus 7 times 2X plus 5?
f(x)= (x-7) /(-2x+7)(2x+5) set -2x+7=0 -2x=-7 x=7/2 set 2x+5=0 2x=-5 x=-5/2 x=7/2 and x=-5/2 are vertical asymptotes.
4x plus 2 equals 2x plus 5?
4x + 2 = 2x + 5 Subtract through by 2x 2x + 2 = 5 Subtract through by 2 2x = 3 Divide through by 2 x = 1.5 ■
2X plus 2 equals X plus 5?
2x+2=x+5 x=3
Factorise 2x plus 7 plus 5?
2x + 7 + 5 = 2x + 12 = 2*x + 2*6 = 2*(x+6)
4x-2 plus 5 equals 2x plus 8?
Simplify 4x + 3 = 2x + 8 2x = 5 x =2½
What is the answer to 2x plus 4 times 4x plus 5?
18x + 5
What is x2 plus x2 mean?
If you have an equation of x2 plus x2, it is the same as saying 2 times x plus 2 times x. This can be written as 2x + 2x or x2 + x2. It is the same, then, as 4x. For example, if x equals 5: 2(5) + 2(5) = 10 + 10 = 20. 20 also equals 4(5).
What is the solution of 2x plus 3 equals 3x plus 5?
2x+3 = 3x+5 2x-3x = 5-3 -x = 2 x = -2
Multiply x plus 3 times x-5?
-2
How do you factor 2x2 plus 13x plus 15?
2x 2+13x+15 = (2x + )(x + ) since the only way to get 2 is 1 times 2. The missing numbers must be filled with with 1 and 15 or 3 and 5 in some order, so by trial and error we get. 2x 2+13x+15 = (2x + 3 )(x + 5 )
