Answer:
-4(8x-7)/7
Step-by-step explanation:
1. Simplify Term.
-8/7 (4x) - 8/7 * -3 + 4/7
-32x/7 - 8/7 * -3 + 4/7
-8/7 * 3
-32x/7 + 24/7 + 4/7
2. Simplify Term.
−
32
x * 24 + 4 divided by 7
-32x + 28 divided by 7
4(-8x + 7) divided by 7
4(-(8x) + 7) divided by 7
3. Rewrite 7 as -1(-7)
4(-(8x) - 1(-7)) divided by 7
4(-(8x - 7)) divided by 7
4. Rewrite -(8x - 7) as -1(8x - 7)
4(-1(8x - 7)) divided by 7
-4(8x - 7)/7
1x1 = 1 !!
Hope this helped.
Answer:
