5(2x + 1) = 75
5*2x + 5*1 = 75
10x + 5 = 75
10x = 75 - 5 = 70
x = 70/10 = 7

Hope this helps!

2 x + 1 = 15

x = 7

5(2x+1)=75
10x + 5= 75
10x = 75-5 (or) 10x +5 - 5= 75 -5
10x = 70
x = 70/10
= 7

x is an algebraic right?

10x + 5 = 75
10x = 70
x = 10

5(2x + 1) = 75
2x + 1 = 75/5
2x + 1 = 15
2x = 15 - 1
x = 14/2
x = 7

5(2x+1)=75
10x+5=75
10x=70
x=70/10
x=7 (75-5=70)

Use The Order OF operations PEMDAS

(2x+1=) 15
5*15=75
Hope This Helped :D

5(2x+1)=75

start with expanding bracket

5 * 2x + 5 * 1 = 75

10 x + 5 = 75

10x = 75 - 5

10x = 70

x = 70/10

x = 7

Dude you realy suck at mathematics. D answer is not 10 its 7.
5(2x+1)=75
10x+5=75 opening bracket
10x=75-5
10x=70
x=70/10
x=7
