Answer:$4.23
Step-by-step explanation:
1/4q = 3w + 3...multiply both sides by 4
q = 4(3w + 3)
q = 12w + 12 <===
Since the denominators are unequal, we find the L.C.M (lowest common multiple) for both denominators.
The L. C. M for 7 and 8 is 56.
Now,
➺
➺
Now that the denominators are equal, we can add them.

Therefore, the numerator is and the denominator is .
Answer:
Step-by-step explanation:
1.
23 + 7 = y +12
y +12 = 30
y = 30 -12
y = 18
2.
a + 3 + 15 = 8 + 8 + 8
a +18 = 24
a = 6
