Question

-5=2(-2)-3
7(-2)-4(-5)=6

Answer 1

-5=2(-2)-3

Simplifying the right side of the equation, we get:

-5 = -4 - 3

Combining like terms, we have:

-5 = -7

Since -5 is not equal to -7, this equation is not true. Therefore, there is no solution.

7(-2)-4(-5)=6

Simplifying both sides of the equation, we have:

-14 + 20 = 6

Combining like terms, we get:

6 = 6

Since 6 is equal to 6, this equation is true. Therefore, 7(-2)-4(-5) = 6.
