make an equation out of the words x+4=2x-19 solve for x to get the number subtract both sides by x 4=x-19 add 19 to both sides 23=x therefore, the number is 23
You must start using a variable which i will use n. A number increased by 4, n+4, is the the same, =, as 19 minus 2 times the number, 19-2n. You must then set up the equation using the description n+4=19-2n. Then solve the equation 3n+4=19 3n=15 n=5 The answer would then be 5.
