Answer:
12 is your answer
Step-by-step explanation:
1.Flip the sides of the equation so 24/34 is on the right side
2. You then cancel the common factor so your 24/34 turns into 12/17
3. Multiply each side by 85. '
Then simply your new equation will look like this;
4y+12=60
4. subtract 12 from both sides
5. Get 48
5. Divide both sides by 4
6. Your answer is 12
3m - 4n - 8 = 3m + (-4n) + (-8)
The trms of the expression: 3m; -4n; -8
