No. If n=5, 80n would be 400, not 28
28+14=42, But 28 x 14=392, Therefore the answer is NO!
4 x z = 28 z = 28/4 z = 7
7x+5-14 = 28 7x = 28+14-5 7x = 37 x = 37/7 = 5.'285714' recurring
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)

No. If n=5, 80n would be 400, not 28
If you mean 28 = 7+y then the solution of the equation is y = 21
28+14=42, But 28 x 14=392, Therefore the answer is NO!
4 x z = 28 z = 28/4 z = 7
2*8 - 4*4 = 0, otherwise insert "does not" before equals.
x = 9 and y = 28
6x = 28 - x (just replace x with 4) 6(4) =? 28 - 4 24 =? 28 - 4 24 = 24 True So that 4 is a solution of the given equation.
7x+5-14 = 28 7x = 28+14-5 7x = 37 x = 37/7 = 5.'285714' recurring

128
It Equals 28. If You Do 7x4 It Will Say 28.
