Answer: a = -35
Step-by-step explanation:
1. -5 = 1/7(a) || GIVEN
2. -5 * (7) = (7) * 1/7(a) || Isolate "a" on one side of the equation by multiplying 7 to the other side.
3. -35 = a
Answer:
-35
I got this by multiplying the numerator by 7. This allows the denominator to be the same as the numerator, thus equalling 1.
1 * a = a
I hope I helped you^_^
x = d/ a + c / a - b
a( x + b ) - c = d
add c on both sides
a( x + b) = d + c
ax + ab = d + c
subtract ab from both sides
ax = d + c - ab divide both sides by a
ax / a = d/ a + c/ a - ab / a
A and B, the suffix "gram" is the giveaway
