8x+5=4x-7
I put x=-3
4 x = -12
x = -3 indeed
Right,
Thanks
Any time :)
To verify if the value x = -3 is a solution to the equation 8x + 5 = 4x - 7, we can substitute the value of x into the equation and see if both sides of the equation are equal.
Starting with the original equation:
8x + 5 = 4x - 7
Substituting x = -3:
8(-3) + 5 = 4(-3) - 7
Simplifying both sides of the equation, we get:
-24 + 5 = -12 - 7
-19 = -19
Since both sides of the equation are equal when x = -3, we can conclude that x = -3 is indeed a solution to the equation.
