Solve X

Does anyone know i have a long exam tomorrow! I really need help please

x= 11

Step-by-step explanation:

4x+5/7 =2x-1/3

multiply both of the equation by 7 first

4x+5/7 times 7 = 2x-1/3 times 7

4x+5= (2x-1)7/3

now multiply 3 to both sides

3(4x+5)= (2x-1)7/3 times 3

3(4x+5)= (2x-1)7

now you should distribute on both sides

(4x times 3)+(5 times 3)= (2x times 7)-( 1 times 7)

12x+15= 14x-7

subtract 12x from both sides

12x-12x+15= 14x-12x-7

15= 2x-7

add 7 to both sides

15+7= 2x-7+7

22= 2x

divided both sides by 2

22/2 = 2x/2

11=x

the answer is 31.27mph
