is this answer true or false, 8x-2=-9+7x?
True
true
Is what answer true or false ??
8x-2 = -9+7x
x = -7
To determine if the equation 8x - 2 = -9 + 7x is true or false, we need to solve it.
First, let's simplify both sides of the equation:
8x - 2 = -9 + 7x
Rearranging the equation, we can group the x terms on one side and the constant terms on the other side:
8x - 7x = -9 + 2
Combining like terms, we get:
x = -7
Now that we have solved the equation, we can check if the answer is true by substituting x = -7 back into the original equation:
8(-7) - 2 = -9 + 7(-7)
-56 - 2 = -9 - 49
-58 = -58
Since both sides of the equation are equal (-58 = -58), we can conclude that the original statement 8x - 2 = -9 + 7x is TRUE when x = -7.
