Work Step by Step

Distribute $3$ on the left side and $2$ on the right side of the equation: $3(5)-3(x)=2(3x)+2(4) \\15-3x=6x+8$ Add $3x$ and subtract $8$ to both sides of the equation then combine like terms: $15-3x+3x-8=6x+8+3x-8 \\7=9x$ Divide $9$ to both sides of the equation: $\frac{7}{9} = \frac{9x}{9} \\\frac{7}{9}=x$
