Here are the answers to the linear equations in real world scenarios quick check:
1: 12x + 210 = 15x + 180
2:100 - 3x = 150 - 5x
3:180-20x =140 -16x ; x = 10
4: 92 + 16x = 104 +13x ; x= 4
5: 120 -7x = 150 - 9x ; x = 15
1: 12x + 210 = 15x + 180
2:100 - 3x = 150 - 5x
3:180-20x =140 -16x ; x = 10
4: 92 + 16x = 104 +13x ; x= 4
5: 120 -7x = 150 - 9x ; x = 15
