Answer:
[tex]x=\frac{26}{5}[/tex]
Step-by-step explanation:
[tex]\frac{10x+4}{7}=8[/tex]
Multiply both sides by 7:
[tex]\longmapsto[/tex] [tex]\frac{7\left(10x+4\right)}{7}=8\times \:7[/tex]
[tex]\longmapsto[/tex] [tex]10x+4=56[/tex]
Subtract 4 from both sides:
[tex]\longmapsto[/tex] [tex]10x+4-4=56-4[/tex]
[tex]\longmapsto[/tex] [tex]10x=52[/tex]
Divide both sides by 10:
[tex]\longmapsto[/tex] [tex]\frac{10x}{10}=\frac{52}{10}[/tex]
[tex]\longmapsto[/tex] [tex]x=\frac{26}{5}[/tex]
