Question

Four less then five times a number is equal to 11

Answer 1

4 less (-4) 5 times a number (5n) is (=) 11 (11)

-4+5n=11
add 4 to both sides
4-4+5n=11+4
0+5n=15
5n=15
divide both sides by 5
5n/5=15/5
1n=3
n=3
the number is 3
 

Answer 2

5x-4= 11 Write the equation
5x = 15 Add 4 to each side
x=3 Divide by 5
