#2.4A
solve linear equations, with integer or fractional coefficients, in one unknown in which the unknown appears on either side or both sides of the equation
\(5x + 8 = 12\)
\(7(x+3) = 5x - 8\)
\(\dfrac{4x+5}{2} = 3\)
Higher only
\(\dfrac{2x-3}{6} + \dfrac{x+2}{3} = \dfrac{5}{2}\)
#2.4B
set up simple linear equations from given data
The three angles of a triangle are \(a°\), \((a + 10)°\), \((a + 20)°\). Find the value of \(a\)
