Answer:
x = 6
Step-by-step explanation:
5x-3 = 2x+15
<h3>i) move 2x to the left-hand side and change its sign</h3>5x-2x-3 = 15
<h3>ii) move -3 to the right-hand side and change its sign</h3>5x-2x = 15+3
<h3>iii) collect like terms</h3>3x = 15+3
<h3>iv) add the numbers</h3>3x = 18
<h3>v) divide both sides of the equation by 3</h3>
