r/3+7=-4?
r/3 = -4 - 7 = -11
r = -33
3x+2y=51
To determine if the equation r/3 + 7 = -4 is true or false, we need to solve for the variable "r." Here's how you can do that:
1. Start by subtracting 7 from both sides of the equation to isolate the term involving "r." This gives us:
r/3 = -4 - 7
2. Simplify the right side of the equation:
r/3 = -11
3. To eliminate the fraction, we can multiply both sides of the equation by 3, which will cancel out the denominator:
3 * (r/3) = 3 * (-11)
r = -33
So, when you solve the equation r/3 + 7 = -4, you find that the value of "r" is -33.
