​

Answer 1

Answer:

$\huge\mathbb\fcolorbox{purple}{lavenderblush}{✰Answer}$

-7x + 2×7 (5) = -7 (10)

-7x + 2 × 35 = -70

-7x + 70 = -70

-7x = -140

x = 20

Answer 2

The value of x in the given equation is 37/7.

Given:

The given equation is

$- 7x + 2 + ( - 7)5 = ( - 7)10$

To Find:

We need to find the value of x.

Solution:

This is a basic problem in arithmetic equations. These problems can be solved by subjecting the variable 'x' and taking all the numerical constants to the right side and solving them finally we get the value of 'x'.

This problem can be solved as:

$- 7x + 2 - 35 = - 70$

$- 7x - 33 = - 70$

$- 7x = - 70 + 33$

$-7x = -37$

$x = 37/7$

Therefore, the value of x is 37/7.
