5x-3 =2x+15 Someone pls help for geometry
1 answer:
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>You might be interested in
Answer:
Step-by-step explanation:
Solve the system of inequalities:
x + 4 < 0
OR:
6x > -12
The first inequality yields the solution:
x < -4
The second inequality gives the solution:
x > -2
The total solution is the disjunction of the individual solutions, i.e., the union of both.
It can be expressed as
