“7a - 17 = 4a +1”<br><br> Step by step pls

Monica [59]

Answer:

a = 6

Step-by-step explanation:

7a-17 = 4a +1 ; Subtract 4a from both sides

3a - 17 = 1 ; Add 17 to both sides

3a = 18 ; Divide both sides by 3

a = 6

Answer:

See below

Step-by-step explanation:

4(x + 5) = 9x + 4x − 34

4x + 20 = 9x + 4x − 34 [Distributive]

4x + 20 = 13x − 34 {Combine Like Terms]

4x - 13x + 20 = 13x - 13x − 34 [Subtractive: -13x both sides]

-5x + 20 = - 34 [Combine Like Terms]

-5x + 20 - 20 = -34 - 20 [Subtractive: - 20 both sides]

-5x = -54 [Combine Like Terms]

x = -54/-5 [Division Property: divide both sides by -5]

x = - 10 4/5
