Find out what X is first. You can't answer that without an equation.
The answer is 7. The equation is x+14=21, so you would find x by doing 21-14=7 x=7
2x + 7 = 33 2x = 33 - 7 2x = 26 X = 26/2 X = 13
tHERE IS NO DIRECT WAY TO FINDS OUT THIOS MATHEMATICAL EQUATION!
x+4.
It is 2*(x+4)
Twice the sum of 'x' and 'y' . . . 2(x+y) The sum of twice 'x' and 'y' . . . (2x+y)
2(x+y) is twice the sum of x and y, and 2x+y is the sum of twice x and y
(28 + 37) x 2 = 130
think about it. x+9=(-7) reverse the equation. (-7)-9=x
Find out what X is first. You can't answer that without an equation.
2 * (x + 7) 2x + 14 ■
If: 2x+8 = 7 then x = -1/2
It is an equation: 3x+11=32 and the value of x is 7
The answer is 7. The equation is x+14=21, so you would find x by doing 21-14=7 x=7
2x + 7 = 33 2x = 33 - 7 2x = 26 X = 26/2 X = 13
