Final answer:
To find the value of x, we need to solve the equations given. We can solve for x by substituting the given values into the equations and solving for the variable.
Step-by-step explanation:
To find the value of x, we need to solve the equations given. We have m22 = 7x + 3, m_3 = 56, and m24 = 12x - 1.
From m_3 = 56, we can solve for x: 56 = 7x + 3, subtract 3 from both sides, 53 = 7x, divide both sides by 7, x = 53/7.
Therefore, x = 7.5714.
