Answer:
x = 10
Step-by-step explanation:
collect like terms, so add 5 to both sides: 2x = 20
divide both sides by 2 to get the value of x: x = 10
x=10
first, add 5 to both sides. the -5 and +5 cancel out, and 15 + 6 is 20. 2x=20. now divide 2 on both sides. the 2s cancel out and 20/2 is 10, so x=10.
