Step-by-Step Solution

Verified
Answer
The simplified form of the algebra expression is \(-4y + 35\)
1Step 1: Distribute the multiplication across the parentheses
Multiply 7 with each term inside the parentheses, that is \(7 \times 3y\) and \(7 \times 5\), to get \(21y + 35\). The expression now becomes \(21y + 35 - 25y\). This step is following the distributive property of multiplication over addition.
2Step 2: Combine like terms
Combine the 'y' terms together and the constants together if there are any. Here we have \(21y\) and \(-25y\) only. Subtract \(25y\) from \(21y\), to get \(-4y\). Thus, the simplified version of the given expression is \(-4y + 35\).\nThis step is following the commutative property of addition.
