25x(207-125)+a=307.025

25 x 82 + a = 307,025

2050 + a = 307,025

a = 307,025 - 2050

a = - 1742,975

25x(207-125)+a=307025

25 x 82 + a = 307025

2050 + a = 307025

a = 307025 - 2050

a = 304975

25×(207-125) + a = 307.025

25×207-125×25 + a = 307.025

a = 307025 -  5175 + 3125

a = 301850 + 3125

a = 304975

25 × (207 - 125) + a = 307.025

25 × 82 + a = 307025

2050 + a = 307025

a = 307025 – 2050

a = 304975
