Answer:
x = 6
Step-by-step explanation:
5x-3 = 2x+15
i) move 2x to the left-hand side and change its sign
5x-2x-3 = 15
ii) move -3 to the right-hand side and change its sign
5x-2x = 15+3
iii) collect like terms
3x = 15+3
iv) add the numbers
3x = 18
v) divide both sides of the equation by 3
[tex] \frac{3x}{3} = \frac{18}{ 3} [/tex]
[tex]x = 6[/tex]
