Answer:
Explanation:
0.2x+2.7x−8.1 = - 5.2x and 6.9+1.1x = 8
Ig you add them it would be 2.8
x =
simplify left side by collecting like terms
2.9x - 8.1 = 6.9 + 1.1x ( subtract 1.1x from both sides )
1.8x - 8.1 = 6.9 ( add 8.1 to both sides )
1.8x = 15 ( multiply both sides by 10 )
18x = 150 ( divide both sides by 18 )
x = =
