Question

here is an equation.
2x - 1 = 5
draw a graph to help solve the equation. then find the solution to the equation.
solution: x = \square

Explanation:

Step1: 移项

将方程\(2x - 1 = 5\)中的\(-1\)移到等号右边，变为\(2x = 5 + 1\)

Step2: 计算右边

计算\(5 + 1 = 6\)，此时方程为\(2x = 6\)

Step3: 求解x

两边同时除以\(2\)，即\(x = \frac{6}{2}\)

Step4: 计算结果

\(\frac{6}{2}=3\)

Answer:

\(3\)
