5(3x-2)=4(2x+1)
(15x-10)=(8x+4)
7x-10=4
7x=14
X=2
Explanation:
I multiplied everything inside the parenthesis by the number on the outside, making the equation 15x-10=8x+4, then I combined like terms, so I subtracted 8x on both sides and added 10 to each side, making the equation 7x=14, this means that 14/7 and 7/7 is the last step, which leaves you with the answer of x=2
