Evaluate
d×9−20p−7
Use b−a=−ba=−ba to rewrite the fraction
d(−9−20p7)
Multiplying or dividing an odd number of negative terms equals a negative
−d×9−20p7
Multiply the terms
−9−20pd×7
Use the commutative property to reorder the terms
−9−20p7d
−9−20p7d=d×43
Use the commutative property to reorder the terms
−9−20p7d=43d
Rewrite the expression
9−20p−7d=43d
Cross multiply
−7d×4=(9−20p)×3d
Simplify the equation
−28d=(9−20p)×3d
Simplify the equation
−28d=(27−60p)d
Add or subtract both sides
−28d−(27−60p)d=0
Calculate
−28d+(−27+60p)d=0
Simplify
More Steps

Evaluate
−28d+(−27+60p)d
Collect like terms by calculating the sum or difference of their coefficients
(−28−27+60p)d
Subtract the numbers
(−55+60p)d
