/ - fraction sign, not a division sign
Solve the following equation
-4=7/33x
a. x=132/7
b. x=-132/7
c. x=-7/132
d. -33/28
The slash mark (/) is both a mark of a fraction and a division. 1/4 is 1 part of 4 or 0.25.
b.
Thank you so much!!
I really appreciate it :)
You're very welcome.
To solve the equation -4 = (7/33)x, we need to isolate x by performing inverse operations.
First, let's multiply both sides of the equation by the reciprocal of the coefficient of x, which is 33/7. This will cancel out the coefficient on the right side:
(-4) * (33/7) = (7/33)x * (33/7)
Simplifying:
-132/7 = x
So the value of x is -132/7.
Out of the given answer choices, the correct option is:
b. x = -132/7
