Answer 1

↬ Hey cherry, bem, neste exercício vamos colocar os termos similares em evidência, somar/subtrair. (Depende do exercício). Simples, não?!

↬ A) $\boxed{\begin{array}{lr}\mathbf{\red{5x + 8x}}\end{array}}\rightarrowtail\boxed{\begin{array}{lr}\mathbf{\red{(5 + 8)x}}\end{array}}\rightarrowtail\boxed{\begin{array}{lr}\mathbf{\red{13x}}\end{array}}$

↬ B) $\boxed{\begin{array}{lr}\mathbf{\red{7y - 10y}}\end{array}}\rightarrowtail\boxed{\begin{array}{lr}\mathbf{\red{(7 - 10)y}}\end{array}}\rightarrowtail\boxed{\begin{array}{lr}\mathbf{\red{ - 3y}}\end{array}}$

↬ C) $\boxed{\begin{array}{lr}\mathbf{\red{9b + 3b + b}}\end{array}}\rightarrowtail\boxed{\begin{array}{lr}\mathbf{\red{(9 + 3 + 1)b}}\end{array}}\rightarrowtail\boxed{\begin{array}{lr}\mathbf{\red{13b}}\end{array}}$

↬ D) $\boxed{\begin{array}{lr}\mathbf{\red{9z - 12z - 15z + 8z}}\end{array}}\rightarrowtail\boxed{\begin{array}{lr}\mathbf{\red{(9 - 12 - 15 + 8)z}}\end{array}}\rightarrowtail\boxed{\begin{array}{lr}\mathbf{\red{ - 10z}}\end{array}}$
