Answer:
[tex]\frac{1}{5} x[/tex]+7=2, x=-25
[tex]\frac{m}{7} -7=3[/tex], m= 105
[tex]\frac{3}{5} x+7=-20, x= -45[/tex]
[tex]-\frac{2}{7} t+5=17, t=-42[/tex]
4.9x+4.2=9.1, x=1
Explanation for last two:
[tex]-\frac{2}{7}t+5=17[/tex]
Step 1: Subtract 5 from both sides.
[tex]\frac{-2}{7} t+5-5=17-5[/tex]
[tex]\frac{-2}{7} t=12[/tex]
Step 2: Multiply both sides by 7/(-2).
[tex](\frac{7}{-2} )*( \frac{-2}{7}t )= (\frac{7}{-2} )*(12)[/tex]
t=−42
4.9x+4.2=9.1
Step 1: Subtract 4.2 from both sides.
4.9x+4.2−4.2=9.1−4.2
4.9x=4.9
Step 2: Divide both sides by 4.9.
[tex]\frac{4.9x}{4.9} \frac{4.9}{4.9}[/tex]
x=1
