Ответ:
x = 10
Subtract 4x from both sides
2x + 15 −4x= −5
Combine 2x and −4x to get −2x
−2x + 15= −5
Subtract 15 from both sides
−2x = −5−15
Subtract 15 from −5 to get −20
−2x = −20
Divide both sides by −2
x = -20/-2
Divide −20 by −2 to get 10
x = 10
Hope this helps!

2x + 15 = 4x - 5
2x - 4x = -5 - 15
-2x = -20
-2x/-2 = -20/-2
x = 10

15/7
Step-by-step explanation: Simplify 6/2 to 3
8x-3=x+12

8x=x+15
Subtract x from both sides
7x=15
Divide both sides by 7
x=15/7
