It could be: 7 7 7 -3 -3 -3 -3
An equivalent expression.
It would be: 3(7-d) as an algebraic expression
?
3 + x/7 Normally an expression like this forms part of an equation such as y = 3 + x/7
7 - ( 3 ÷ v )
7
-4
what you want
3(x^2 +7) is the same as 3x^2 + 21 to find the answer of x set an value to the equation
3(y+7)
It is: 3v-7
7 and 3 - 2x are factors of 21 - 14x
