x= $- \frac{15.32}{9.38}; = - \frac{10.72}{9.38}$ $-15.32/9.38; =-10.72/9.38$

Simplifying the equation, it becomes 13.02+ 26.88x= 17.5 x $\pm$ $+-$ 2.3

Or, 26.88x-17.5x =-13.02 $\pm$ $+-$ 2.3

9.38x= -15.32 or -10.72

x= $- \frac{15.32}{9.38}; = - \frac{10.72}{9.38}$ $-15.32/9.38; =-10.72/9.38$

How do you solve for x in 4.2(3.1+6.4x)=17.5x±2.34.2(3.1+6.4x)=17.5x+-2.3?
