3x + 7 = -4x + 28 implies 7x + 7 = 28

Yes that is correct

r = 4

It is an equation of: 5x+3 = 28 and its solution is x = 5 5 times x plus 3 equals 28. Subtract 3 from both sides of the equation. 5 times x equals 25. Divide both sides of the equation by 5. x equals 5. (stop)

n = 28

Good work ! Did you have a question you wanted to ask ?

22+22+28+28=100.

the equation can also be written 2x+28=152, subtract 28 from each side :2x=124, divide each side by 2 and you get x=62

28 in this case.

This equation is unsolvable without knowing one of the values of either x or y.

it equals 28

it is 28

Set up the equation and solve for z: 28 + z = 56 (next, subtract 28 from each side of the equaition to solve) z = 28

k=8k+28 k-8k=28 -7k=28 k=-(28/4) k=-4

7x-y-28 = 0

-6z + 2 = 3z + 4z + 28 Add 6z to both sides: 2 = 3z + 4z + 28 + 6z = 28 + 13z Subtract 28 from both sides: - 26 = 13z Divide both sides by 13: -2 = z

25 + 28 + 29 = 82

y=-(8/7)x+4 Therefore, the slope= -(8/7)

subtraction; 80-y= 52. 28+52 =80

It is an equation and the value of a is 7

Using the quadratic equation formula:- x = -4.706950048 and x = 0.849071913

18 + 10 + 28 + 10 = 66
