2 is multiplied by g
2 x g = 2g
2g
It is an expression that can be simplified to: 2g -8
step by step: 15-g=23-2g transpose -2g to other side 15-g+2g=23-2g+2g cancel 2g on the right side, and do operation on the left side 15+g=23 transpose 15 to other side to obtain variable=constant 15-15+g=23-15 cancel 15 on the left side, and do operation on the right side g=8 you already have the value of g Normal way: 15-g=23-2g 2g-g=23-15 g=8 I hope this could help you...
That looks like the description of an EXPRESSION. However, an expression need not have "at least one operation"; a single number, or variable, is a perfectly valid expression.
It is an algebraic expression.
3020 is a number, not an operation. A number cannot have an inverse operation.
It is an algebraic expression.
