4x^2+11x-4x^2+28=49
You asked:
Solve the equation \(4 {x}^{2} + 11 x - 4 {x}^{2} + 28 = 49\) for the variable \(x\).
MathBot Answer:
The solution is: \[x = \frac{21}{11} = 1.\overline{90}\]
\[\begin{aligned}4 {x}^{2} + 11 x - 4 {x}^{2} + 28 &= 49\\11 x + 28 &= 49\\11 x &= 21\\x &= \frac{21}{11}\end{aligned}\]
