five times the sum of a number and 8 is -15.
how?
5
the sum of 8 and 4 times a number is 36
8(5+4)+7 = 79
The sum of 8 and 5 is 13. There is then no number with which to calculate its product.
This is simple algebra. Let the unknown number be n. Then the sum of this number and 8 = n + 8.
(3a-8) + 5x(a)
5
8(5 + x), or 8x + 40.
the sum of 8 and 4 times a number is 36
8(5+4)+7 = 79
5*n + (n - 8) = 5n + n - 8 = 6n - 8
The sum of 8 and 5 is 13. There is then no number with which to calculate its product.
This is simple algebra. Let the unknown number be n. Then the sum of this number and 8 = n + 8.
5(x+3)+8
Not necessarily. If the number is 0, then the sum of 8 times the number and -192 is -192.

4(x + 5) = 2x + 8 4x + 20 = 2x + 8 2x = -12 x = -6
