Solve -5/8y=-20
\[ \frac{-5}{8y}=-20\] or \[\frac{-5}{8}y=-20\]?
the latter
answer to second one is \[y=-20\times \frac{8}{-5}=\] \[y=32\]
-(5)/(8)*y=-20 Multiply -5 by y to get -5y. -(5y)/(8)=-20 Multiply each term in the equation by 8. -(5y)/(8)*8=-20*8 Cancel the common factor of 8 in the denominator of the first term -(5y)/(8) and the second term 8. -(5y)/(<X>8<x>)*<X>8<x>=-20*8 Reduce the expression by removing the common factor of 8 in the denominator of the first term -(5y)/(8) and the second term 8. -5y*1=-20*8 Multiply -5y by 1 to get -5y. -5y=-20*8 Multiply -20 by 8 to get -160. -5y=-160 Divide each term in the equation by -5. -(5y)/(-5)=-(160)/(-5) Move the minus sign from the denominator to the front of the expression. -(-(5y)/(5))=-(160)/(-5) Cancel the common factor of 5 in -(5y)/(5). -(-(<X>5<x>y)/(<X>5<x>))=-(160)/(-5) Remove the common factors that were cancelled out. -(-y)=-(160)/(-5) Multiply - by the -y inside the parentheses. -*-y=-(160)/(-5) Multiply - by -y to get y. y=-(160)/(-5) Move the minus sign from the denominator to the front of the expression. y=-(-(160)/(5)) Cancel the common factor of 5 in -(160)/(5). y=-(-(^(32)<X>160<x>)/(<X>5<x>)) Remove the common factors that were cancelled out. y=-(-32) Multiply - by the -32 inside the parentheses. y=-*-32 Multiply - by -32 to get 32. y=32
