Question

2 more than a certain number is 15 less than the product of 7/8 and the number

Answer 1

Answer:

Solution  is N = -136

Step-by-step explanation:

2+N= .875n-15

2=-.125n-15

17=-.125n

17/-.125=-136

2+(-136)=.875(-.125)-15

-134 = -134

Answer 2

Equations are used to show the relationship between expressions and numbers. The number that fits the given scenario is -136.

Let the number be x.

2 more than x is represented as $2 + x$

15 less than the product of $\frac 78$ and x is represented as: $\frac 78x - 15$

So, the equation is:

$2 + x = \frac 78x - 15$

The solution is as follows:

Collect like terms

$x -\frac 78x= - 15-2$

$x -\frac 78x= - 17$

Take LCM

$\frac{8-7}{8}x= - 17$

$\frac{1}{8}x= - 17$

Multiply through by 8

$8 \times \frac{1}{8}x= - 17 \times 8$

$x= - 136$

Hence, the number is -136.
