calcule as equaçoes
a]10=x+1
b]7=x+8
c]-3=x+10

Answer 1

$\boxed{\begin{array}{lr} a)\\10=x+1\\10-1=x\\9=x\\x=9 \end{array}}\\\\\boxed{\begin{array}{lr} b)\\7=x+8\\-x=8-7\\-x=1\\x=-1 \end{array}}\\\boxed{\begin{array}{lr} c)\\-3=x+10\\-x=10+3\\-x=13\\x=-13 \end{array}}$

Explicação passo-a-passo:

$10 = x + 1 \\ 10 - x = 1 \\ - x = 1 - 10 \\ - x = - 9 \\ x = 9$

$7 = x + 8 \\ 7 - x = 8 \\ - x = 8 - 7 \\ - x = 1 \\ x = - 1$

$- 3 = x + 10 \\ - 3 - x = 10 \\ - x = 10 + 3 \\ - x = 13 \\ x = - 13$
