{x+y=5x+150y=9
x=741149,y=4149
Step 1 :{x+y=5x+150y=9
Step 2 :Multiply the first equation by −150:
Step 3 :−150(x+y)=−750
Step 4 :−150x−150y=−750
Step 5 :Add the new equation to the second equation:
Step 6 :−150x−150y+x+150y=−750+9
Step 7 :−149x=−741
Step 8 :x=741149
Step 9 :Substitute the value of x into the first equation:
Step 10 :741149+y=5
Step 11 :y=5−741149
Step 12 :y=4149
Step 13 :x=741149,y=4149
