Spencer is 51 years younger than holly seven years ago holly's age was four times spencer's age how old is spencer now

X= Holly's age
x-51= Spencer's age

Holly's age equals 4 multiplied by Spencer's age, subtracted by 7 (because it was 7 years ago).

EQUATION:
x - 7 = 4(x-51) - 7
multiply 4 by all in parentheses

x - 7= (4*x) + (4*-51) - 7
multiply inside parentheses

x - 7= 4x - 204 - 7
combine like terms

x - 7= 4x -211
add 211 to both sides

x + 204= 4x
subtract x from both sides

204= 3x
divide both sides by 3

68= x

Holly's Age:
x= 68

Spencer's Age:
substitute x=68 to find Spencer's age
=x-51
=68-51
=17

ANSWER:
Holly is 68 years old and Spencer is 17 years old.

Hope this helps! :)
