\[6 \cdot x = 24 \qquad 35 : x = 7 \qquad y : 4 = 7\]
\[\textcolor{#e03131}{\boldsymbol{x = 4;}}\quad \textcolor{#e03131}{\boldsymbol{x = 5;}}\quad \textcolor{#e03131}{\boldsymbol{y = 28}}\]
\(\textcolor{#808080}{{6 \cdot 4 = 24}\text{,}}\) \(\textcolor{#808080}{{35 : 5 = 7}\text{,}}\) \(\textcolor{#808080}{{28 : 4 = 7}\text{.}}\)
2) Запиши решения уравнений и сделай проверку.
\[\begin{aligned} 14 + x &= 34 \\ x &= 34 - 14 \\ x &= \textcolor{#e03131}{\mathbf{20}} \\ \text{Проверка: }14 + 20 &= 34 \\ \textcolor{#e03131}{\mathbf{34}} &= \textcolor{#e03131}{\mathbf{34}} \end{aligned}\]
\[\begin{aligned} 75 - x &= 8 \\ x &= 75 - 8 \\ x &= \textcolor{#e03131}{\mathbf{67}} \\ \text{Проверка: }75 - 67 &= 8 \\ \textcolor{#e03131}{\mathbf{8}} &= \textcolor{#e03131}{\mathbf{8}} \end{aligned}\]
\[\begin{aligned} y - 20 &= 47 \\ y &= 47 + 20 \\ y &= \textcolor{#e03131}{\mathbf{67}} \\ \text{Проверка: }67 - 20 &= 47 \\ \textcolor{#e03131}{\mathbf{47}} &= \textcolor{#e03131}{\mathbf{47}} \end{aligned}\]
