-60a=7\left(1\times 20+17\right)
Multiply both sides of the equation by 140, the least common multiple of 7,20.
-60a=7\left(20+17\right)
Multiply 1 and 20 to get 20.
-60a=7\times 37
Add 20 and 17 to get 37.
-60a=259
Multiply 7 and 37 to get 259.
a=\frac{259}{-60}
Divide both sides by -60.
a=-\frac{259}{60}
Fraction \frac{259}{-60} can be rewritten as -\frac{259}{60} by extracting the negative sign.
