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
Answer:
28.5
Step-by-step explanation:
This is because each number increases by half of the previous number,
the difference between 10 and 18 is eight, which when halved is 4,
the difference between 18 and 24 is four, the pattern then carries on...

The answer is 16 use pendas
What it is basically asking is if Y = -4, find the value of x in the equation 6x + 7y = 4x + 4y
To solve this you just need to plug in -4 for y and solve for x
6x + 7(-4) = 4x + 4(-4)
6x - 28 = 4x - 16
Now isolate x by adding 28 to both sides
6x - 28 + 28 = 4x - 16 + 28
6x = 4x + 8
and subtract 4x from both sides
6x - 4x = 4x - 4x + 8
2x = 8
divide both sides by 2
2/2x = 8/2
x = 4
x = 4, y = -2
Answer: (4, - 2)
