6*(x + 7)
The sum of number and four times a number is 25 write in algebraic expression
90
7x4+8
2 + 2x = 36
7x +9 = 6x
6*(x + 7)
The sum of number and four times a number is 25 write in algebraic expression
16x(1+a)

7x4+8
2*(n+15) = 6n
6x + 4 = 5x x = -4
2 + 2x = 36
x2 + 9 = 36
Let's call the number XTwice the number would be 2XFour times the same number would be 4XThe sum of these two is 2X + 4X = 6XThe answer is therefore six times the number.
24(x + 2.25)
