It is a linear equation in one variable, x.
88+x=3x+22 88=2x+22 66=2x x=33
Add the coefficients of the variable term X. 2 + 3 + 8 = 13X
no
It is an expression in two variable: it is NOT an equation. There is no standard form for expressions.
Yes, because neither variable has an exponent different from ' 1 '.
3x + 2 = 3x + 6 This is not possible.
3x plus 9 equals what?
(2, -1)
Their graphs are.
